* Implement hardware accelerated CRC32 and SHA1, use them if possible. CRC32's generic function is also replaced with zlib's as it is much more performant than our implementation Full hash of a ~731MB disc took only ~369 ms with this, and the generic CRC32 isn't so far behind at ~659 ms SHA1 should perform 4x faster if the user's CPU supports the SHA instructions.

LibBizHash is the unmanaged side for BizHawk's hashing.
CRC32 code is taken from zlib-ng with massive slashing of code and various tweaks. This code is licensed under the zlib license. SHA1 is code is taken from SHA-Intrinsics with some tweaks. This code is under the public domain.
To build, just do make in this directory. Note gcc 10 or later is required (due to missing intrinsics in older gcc versions)
