Hi guys, here's my first actual compressor, my goal was to make a faster and more memory efficient utility like srep, superduper is just short for "super deduplication" (it sounded snazzy). Its performance is pretty good, with encoding generally around 200 MB/s and decoding near 2 GB/s on an overclocked pentium g3258.

Let me know if you encounter any bugs.
