             * - mode (Number|Boolean): 0..6 for corresponding Z_NO_FLUSH..Z_TREE modes.
             *   See constants. Skipped or `false` means Z_NO_FLUSH, `true` means Z_FINISH.
             *
             * Sends input data to deflate pipe, generating [[Deflate#onData]] calls with
             * new compressed chunks. Returns `true` on success. The last data block must have
             * mode Z_FINISH (or `true`). That will flush internal pending buffers and call
             * [[Deflate#onEnd]]. For interim explicit flushes (without ending the stream) you
             * can use mode Z_SYNC_FLUSH, keeping the compression context.
             *
             * On fail call [[Deflate#onEnd]] with error code and return false.
             *
             * We strongly recommend to use `Uint8Array` on input for best speed (output
             * array format is detected automatically). Also, don't skip last param and always
             * use the same type in your code (boolean or number). That will improve JS speed.

             * - mode (Number|Boolean): 0..6 for corresponding Z_NO_FLUSH..Z_TREE modes.
             *   See constants. Skipped or `false` means Z_NO_FLUSH, `true` means Z_FINISH.
             *
             * Sends input data to inflate pipe, generating [[Inflate#onData]] calls with
             * new output chunks. Returns `true` on success. The last data block must have
             * mode Z_FINISH (or `true`). That will flush internal pending buffers and call
             * [[Inflate#onEnd]]. For interim explicit flushes (without ending the stream) you
             * can use mode Z_SYNC_FLUSH, keeping the decompression context.
             *
             * On fail call [[Inflate#onEnd]] with error code and return false.
             *
             * We strongly recommend to use `Uint8Array` on input for best speed (output
             * format is detected automatically). Also, don't skip last param and always
             * use the same type in your code (boolean or number). That will improve JS speed.

               When large enough input and output buffers are supplied to inflate(), for
               example, a 16K input buffer and a 64K output buffer, more than 95% of the

                    LEN -- ran out of enough output space or enough available input
                    TYPE -- reached end of block code, inflate() to interpret next block
                    BAD -- error in block data
            
               Notes:
            
                - The maximum input bits used by a length/distance pair is 15 bits for the
                  length code, 5 bits for the length extra, 15 bits for the distance code,
                  and 13 bits for the distance extra.  This totals 48 bits, or six bytes.
                  Therefore if strm.avail_in >= 6, then there is enough input to avoid
                  checking for available input while decoding.
            
                - The maximum bytes that a single length/distance pair can output is 258
                  bytes, which is the maximum length that can be coded.  inflate_fast()
                  requires strm.avail_out >= 258 for each loop to avoid checking for
                  output space.

                 Process a set of code lengths to create a canonical Huffman code.  The
                 code lengths are lens[0..codes-1].  Each length corresponds to the
                 symbols 0..codes-1.  The Huffman code is generated by first sorting the
                 symbols by length from short to long, and retaining the symbol order
                 for codes with equal lengths.  Then the code starts with all zero bits
                 for the first code of the shortest length, and the codes are integer
                 increments for the same length, and zeros are appended as the length
                 increases.  For the deflate format, these bits are stored backwards
                 from their more natural integer increment ordering, and so when the
                 decoding tables are built in the large loop below, the integer codes
                 are incremented backwards.
              
                 This routine assumes, but does not check, that all of the entries in
                 lens[] are in the range 0..MAXBITS.  The caller must assure this.
                 1..MAXBITS is interpreted as that code length.  zero means that that
                 symbol does not occur in this code.
              
                 The codes are sorted by computing a count of codes for each length,
                 creating from that a table of starting indices for each length in the
                 sorted table, and then entering the symbols in order in the sorted
                 table.  The sorted table is work[], with that space being provided by
                 the caller.
              
                 The length counts are used for other purposes as well, i.e. finding
                 the minimum and maximum length codes, determining if there are any
                 codes at all, checking for a valid set of lengths, and looking ahead
                 at length counts to determine sub-table sizes when building the
                 decoding tables.

                 Create and fill in decoding tables.  In this loop, the table being
                 filled is at next and has curr index bits.  The code being used is huff
                 with length len.  That code is converted to an index by dropping drop
                 bits off of the bottom.  For codes where len is less than drop + curr,
                 those top drop + curr - len bits are incremented through all values to
                 fill the table with replicated entries.
              
                 root is the number of index bits for the root table.  When len exceeds
                 root, sub-tables are created pointed to by the root entry with an index
                 of the low root bits of huff.  This is saved in low to check for when a
                 new sub-table should be started.  drop is zero when the root table is
                 being filled, and drop is root when sub-tables are being filled.
              
                 When a new sub-table is needed, it is necessary to look ahead in the
                 code lengths to determine what size sub-table is needed.  The length
                 counts are used for this, and so count[] is decremented as codes are
                 entered in the tables.
              
                 used keeps track of how many table entries have been allocated from the
                 provided *table space.  It is checked for LENS and DIST tables against
                 the constants ENOUGH_LENS and ENOUGH_DISTS to guard against changes in
                 the initial root table size constants.  See the comments in inftrees.h
                 for more information.
              
                 sym increments through all symbols, and the loop terminates when
                 all codes of length max, i.e. all codes, have been processed.  This
                 routine permits incomplete codes, so another loop after this one fills
                 in the rest of the decoding tables with invalid code markers.

            // a transform stream is a readable/writable stream where you do
            // something with the data.  Sometimes it's called a "filter",
            // but that's not a great name for it, since that implies a thing where
            // some bits pass through, and others are simply ignored.  (That would
            // be a valid example of a transform, of course.)
            //
            // While the output is causally related to the input, it's not a
            // necessarily symmetric or synchronous transformation.  For example,
            // a zlib stream might take multiple plain-text writes(), and then
            // emit a single compressed chunk some time in the future.
            //
            // Here's how this works:
            //
            // The Transform stream has all the aspects of the readable and writable
            // stream classes.  When you write(chunk), that calls _write(chunk,cb)
            // internally, and returns false if there's a lot of pending writes
            // buffered up.  When you call read(), that calls _read(n) until
            // there's enough pending readable data buffered up.
            //
            // In a transform stream, the written data is placed in a buffer.  When
            // _read(n) is called, it transforms the queued up data, calling the
            // buffered _write cb's as it consumes chunks.  If consuming a single
            // written chunk would result in multiple output chunks, then the first
            // outputted bit calls the readcb, and subsequent chunks just go into
            // the read buffer, and will cause it to emit 'readable' if necessary.
            //
            // This way, back-pressure is actually determined by the reading side,
            // since _read has to be called to start processing a new chunk.  However,
            // a pathological inflate type of transform can cause excessive buffering
            // here.  For example, imagine a stream where every byte of input is
            // interpreted as an integer from 0-255, and then results in that many
            // bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in
            // 1kb of data being output.  In this case, you could write a very small
            // amount of input, and end up with a very large amount of output.  In
            // such a pathological inflating mechanism, there'd be no way to tell
            // the system to stop doing the transform.  A single 4MB write could
            // cause the system to run out of memory.
            //
            // However, even in such a pathological case, only a single written chunk
            // would be consumed, and then the rest would wait (un-transformed) until
            // the results of the previous transformed chunk were consumed.
