Start a chunked conversion. While it accepts any Sink
taking List's, the optimal sink to be passed as sink is a
ByteConversionSink.
Source
ByteConversionSink startChunkedConversion(Sink<List<int>> sink) {
if (sink is! ByteConversionSink) {
sink = new ByteConversionSink.from(sink);
}
return new _ZLibDecoderSink(sink, windowBits, dictionary, raw);
}
