Title: Pull request for an scrypt method that takes the salt as an argument.

I made changes to add an scrypt method that allows for passing in the salt in the rare case where you actually want to hash something to the same hash value. An example is hashing credit card numbers in order to detect duplicates without storing the actual card number.

The changes also include full unit test coverage to ensure no breakage.

Thanks for your consideration.
