A few non-generic functions like HashStrBytes have been kept for
backwards compatibility, so this package should continue to work with
older Go versions (as long as they support generics).
Previously, we implemented individual bytealg functions via linknaming, and had to update them every once in a while when we hit linker errors.
Instead, this change reimplements the bytealg package in pure Go.
If something is missing, it will cause a compiler error rather than a linker error.
This is easier to test and maintain.
