Why no io.Reader and io.Writer interface for snappy? about snappy HOT 2 CLOSED

I've taken a go at implementing Reader/Writers for the framing format at 
https://github.com/twotwotwo/sz/ but beware: there're no tests (I've only 
played with the trivial toy program in cmd/sz) and I played the dangerous game 
of tweaking code right before pushing, so there may be embarrassing mistakes, 
caveat emptor, etc. 

I don't love the current design--it internally buffers up 64KB blocks so that 
tiny writes don't lead to a bad compression ratio. It should probably expose 
Reader/Writers that don't buffer to the extent possible, and convenience 
functions that wrap them in bufio.Reader/Writer.
