XXH3 Implementation for Zig STD (#17530)
XXH3 is the faster alternative to XXH64 which utilizes SIMD when hashing large chunks of memory and similar mixing to WyHash (64x64 -> 128 mul) for smaller inputs. Co-authored-by: Reixcon226 <87927264+Rexicon226@users.noreply.github.com> --------- Co-authored-by: kprotty <kbutcher6200@gmail.com>
