This is an API-breaking update!

Internally, HashType was defined as an enumeration, which caused issues if minor- or patch-version mismatches occurred. HashType has been converted into a distinct type that disallows this sort of mismatching behavior. Any implementers that relied on the enumeration behavior will have to use HashType.AllHashes to get all possible values or build sets of HashType values another way.

I apologize for the inconvenience of this change, but this should make it easier to add new checksum and hash types in the future without worrying about backward compatibility to this point.
