An input stream object that uses zlib to decompress (inflate) the input from another source stream on-the-fly.
Attach an IDecompressStream to an existing istream that provides compressed data, and read the corresponding uncompressed data from the IDecompressStream.
Seeking is not supported.
explicit IDecompressStream(std::istream *source, bool owns_source)
Resets the ZStream to empty, but does not actually close the source istream unless owns_source was true.
