AFL crash

[aschampion]

The AFL fuzz I started in #37 found a crash (after 37 days and 2 cycles!) where the decompressed data does not match the input (with CompressionOptions::default()). I'll look into in the next few days and also PR the fuzz binary. In the meantime here's the crash input.

Oh wow, will look into it in a week when I have time if no one else has found the issue by then.

Last I checked there were 3 more unique crashes. I should note all of these are just the compression roundtrip data not matching the original data; no crashes in the library. I'll upload them next time I'm at that computer.
