+ * inflate(data[, options]) -> Uint8Array|Array|String
+ * - data (Uint8Array|Array|String): input data to decompress.
+ * - options (Object): zlib inflate options.
+ *
+ * Decompress `data` with inflate/ungzip and `options`. Autodetect
+ * format via wrapper header by default. That's why we don't provide
+ * separate `ungzip` method.
+ *
+ * Supported options are:
+ *
+ * - windowBits
+ *
+ * [http://zlib.net/manual.html#Advanced](http://zlib.net/manual.html#Advanced)
+ * for more information.
+ *
+ * Sugar (options):
+ *
+ * - `raw` (Boolean) - say that we work with raw stream, if you don't wish to specify
+ * negative windowBits implicitly.
+ * - `to` (String) - if equal to 'string', then result will be converted
+ * from utf8 to utf16 (javascript) string. When string output requested,
+ * chunk length can differ from `chunkSize`, depending on content.
+ *
+ *
+ * ##### Example:
+ *
+ * ```javascript
+ * var pako = require('pako')
+ * , input = pako.deflate([1,2,3,4,5,6,7,8,9])
+ * , output;
+ *
+ * try {
+ * output = pako.inflate(input);
+ * } catch (err)
+ * console.log(err);
+ * }
+ * ```

+ 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

+ 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
