Decode with endOnOutputSize

[gibbed]

It doesn't appear that decoding with endOnOutputSize is exposed. Is there any plan to make this available?

I'm after partial decoding of data, where I know the uncompressed and compressed sizes, but would like to do partial decoding to get at a file header before I choose to decode the entire file. Currently if I try to do this with LZ4Codec.Decode it returns -1 without any bytes written to my output buffer.

The relevant underlying C# implementation is all set to internal, so I can't just readily use that without making my own build of this library, I think.
