64Bit file hashing algorithm
For when security isn't the main concern and we just want to verify that our files were copied properly.
Approximately 3X+ the speed of md5sum.
Benchmarked on Artix Linux(x64) inside a ramdisk.
Build with
chmod +x build && ./build
Run with
./crush fileName
Note: ./build dumps compilation information so you can see what escapes to heap. Only values outside the core hasher should.
