         * It should be in the range 8..15 for this version of the library. The default value is 15 if inflateInit is used instead.
         * windowBits must be greater than or equal to the windowBits value provided to deflateInit2() while compressing,
         * or it must be equal to 15 if deflateInit2() was not used. If a compressed stream with a larger window size is given as input,
         * inflate() will return with the error code Z_DATA_ERROR instead of trying to allocate a larger window.
         * WindowBits can also be zero to request that inflate use the window size in the zlib header of the compressed stream.
         * WindowBits can also be -8..-15 for raw inflate. In this case, -windowBits determines the window size.
         * inflate() will then process raw deflate data, not looking for a zlib or gzip header,
         * not generating a check value, and not looking for any check values for comparison at the end of the stream.
         * This is for use with other formats that use the deflate compressed data format such as zip. Those formats provide their own check values.
         * If a custom format is developed using the raw deflate format for compressed data, it is recommended that a check value such as an Adler-32 or
         * a CRC-32 be applied to the uncompressed data as is done in the zlib, gzip, and zip formats. For most applications,
         * the zlib format should be used as is. Note that comments above on the use in deflateInit2() applies to the magnitude of windowBits.WindowBits
         * can also be greater than 15 for optional gzip decoding. Add 32 to windowBits to enable zlib and gzip decoding with automatic header detection,
         * or add 16 to decode only the gzip format. If a gzip stream is being decoded, strm->adler is a CRC-32 instead of an Adler-32.
         * Unlike the gunzip utility and gzread(), inflate() will *not* automatically decode concatenated gzip members. Inflate() will return
         * Z_STREAM_END at the end of the gzip member. The state would need to be reset to continue decoding a subsequent gzip member.
