Sets file_info in compressor. If non-null, and compressor's
#GZlibCompressor:format property is gio.types.ZlibCompressorFormat.Gzip,
it will be used to set the file name and modification time in
the GZIP header of the compressed data.
Note: it is an error to call this function while a compression is in
progress; it may only be called immediately after creation of compressor,
or after resetting it with gio.converter.Converter.reset.
