Support more decode formats #97
Description
Encode supports multiple formats allowing zeeo-copy transformations. Decode only works with InputStreams, which forces extra transformations (e.g. the format could decode byte[] directly, but we need to wrap it into InoutStream). Decode should support the same formats too.
