				 * - data (Uint8Array|Array|ArrayBuffer|String): input data
				 * - mode (Number|Boolean): 0..6 for corresponding Z_NO_FLUSH..Z_TREE modes.
				 *   See constants. Skipped or `false` means Z_NO_FLUSH, `true` meansh 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.
				 *
				 * For regular `Array`-s make sure all elements are [0..255].

				 Decode literal, length, and distance codes and write out the resulting
				 literal and match bytes until either not enough input or output is
				 available, an end-of-block is encountered, or a data error is encountered.
				 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
				 inflate execution time is spent in this routine.

				 Entry assumptions:

				 state.mode === LEN
				 strm.avail_in >= 6
				 strm.avail_out >= 258
				 start >= strm.avail_out
				 state.bits < 8

				 On return, state.mode is one of:

				 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.
