Let users be polymorphic in choice of hash function

[jberryman]

It might be nice to support allowing users to write code that was hash-function-agnostic, letting their users choose the hash function they prefer. For example someone might create a hash table library using hashabler and allow their users to swap in FNV-1a or siphash or a hash function of their own choosing.

I'm not quite sure what this would look like, especially since I'm not convinced the way I've structured the current Hash and Hashable classes is that great.

Please comment if you're interested in this feature and mention your use case.

I've created a set of Hash types of different widths in v1.0. This feature can be done in a separate package if anyone wants it I think.
