code: function deflateRaw(input, options) {
    options = options || {};
    options.raw = true;
    return deflate(input, options);
  }
docs: deflateRaw(data[, options]) -> Uint8Array|Array|String
  - data (Uint8Array|Array|String): input data to compress.
  - options (Object): zlib deflate options.
  
  The same as [[deflate]], but creates raw data, without wrapper
  (header and adler32 crc).
