Also move the non crypto hash funcs into this new package. This is much faster than e.g. MD5, especially for larger inputs: ``` BenchmarkXxHash/xxHash_43-10 9917955 112.2 ns/op 56 B/op 4 allocs/op BenchmarkXxHash/mdb5_43-10 6017239 204.1 ns/op 96 B/op 3 allocs/op BenchmarkXxHash/fnv32a_43-10 14407333 82.30 ns/op 16 B/op 1 allocs/op BenchmarkXxHash/xxHash_4300-10 2916892 409.7 ns/op 56 B/op 4 allocs/op BenchmarkXxHash/mdb5_4300-10 159748 7491 ns/op 4912 B/op 3 allocs/op BenchmarkXxHash/fnv32a_4300-10 218210 5510 ns/op 16 B/op 1 allocs/op ``` Fixes #12635
