+ * 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
