Fix memory bug in SnappyNifSink::Append

Previously `SnappyNifSink` assumed that `GetAppendBuffer` was always
called before `Append`. This turned out to be an invalid assumption.
This was definitely in the land of "How did that even work?". The simple
fix is simple.

This also pre-allocates the write buffer to 8192 bytes which just saves
us from the initial re-allocation on first `Append` since we allocated a
zero length buffer initially.

performance tests

Snappy is much faster than zlib's deflate compression, specially for reasonably large amounts of data. Here follow a few basic tests.
