I've selected a chunk size of 8000 bytes rather arbitrarily, but it
seems to work just fine. The bigger problem is that the simplified
final fraction makes the running fraction in decompression's foldl
more complicated as time goes on, making it around 50 times slower
than compression. It takes just under an hour to decompress the
Great Gatsby.
Word16 seems to give the best compression ratio. It takes a very long
time to run on >5MB files. Decompression is not implemented yet, but I'm
confident it works.
