* new Deflate(options)

*
* Creates new deflator instance with specified params. Throws exception

*
* - `level`
* - `windowBits`
* - `memLevel`
* - `strategy`
*
* [http://zlib.net/manual.html#Advanced](http://zlib.net/manual.html#Advanced)
* for more information on these.
*
* 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
*
* ##### Example:
*
* ```javascript
* var pako = require('pako')
* , chunk1 = Uint8Array([1,2,3,4,5,6,7,8,9])
* , chunk2 = Uint8Array([10,11,12,13,14,15,16,17,18,19]);
*
* var deflate = new pako.Deflate({ level: 3});

* deflate.push(chunk1, false);
* deflate.push(chunk2, true); // true -> last chunk
