+ * - `strategy`

+ *
+ * [http://zlib.net/manual.html#Advanced](http://zlib.net/manual.html#Advanced)

+ * Additional options, for internal needs:
+ *
+ * - `chunkSize` - size of generated data chunks (16K by default)
+ * - `raw` (Boolean) - do raw deflate
+ * - `gzip` (Boolean) - create gzip wrapper
+ * - `to` (String) - if equal to 'string', then result will be "binary string"
+ *    (each char code [0..255])
+ * - `header` (Object) - custom header for gzip
+ *   - `text` (Boolean) - true if compressed data believed to be text
+ *   - `time` (Number) - modification time, unix timestamp
+ *   - `os` (Number) - operation system code
+ *   - `extra` (Array) - array of bytes with extra data (max 65536)
+ *   - `name` (String) - file name (binary string)
+ *   - `comment` (String) - comment (binary string)
+ *   - `hcrc` (Boolean) - true if header crc should be added

+   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

+   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

+
+   When a new sub-table is needed, it is necessary to look ahead in the

+   counts are used for this, and so count[] is decremented as codes are
