Implements abstract com.ning.compress.lzf.ChunkEncoder.tryCompress.

Doc from com.ning.compress.lzf.ChunkEncoder.tryCompress.

Main workhorse method that will try to compress given chunk, and return end position (offset to byte after last included byte). Result will be "raw" encoded contents without chunk header information: caller is responsible for prepending header, if it chooses to use encoded data; it may also choose to instead create an uncompressed chunk.

Returns:int

Output pointer after handling content, such that result - originalOutPost is the actual length of compressed chunk (without header)
