ChunkCodecLibLzma has a stable API now, allows setting a preset (this is what liblzma calls compression level), and removes the extra copy when compressing.

I have the preset at the default of UInt32(6), but this can be increased to UInt32(9) for more compression.

Also, since the decompressed size is already known, I'm passing it as a max_size and size_hint to decode for better memory usage.

This looks great, thanks Nathan. Also, cool, I see you're at UMD. I was raised in the area, Go Terps!
