/// Initializes the decompression dictionary from the given uncompressed byte sequence. This function must be called immediately after a call of <see cref="inflate" /> if this call returned <see cref="ZLibResultCode.Z_NEED_DICT" />. The dictionary chosen by the compressor can be determined from the Adler32 value returned by this call of <see cref="inflate" />. The compressor and decompresser must use exactly the same dictionary.
