Support for UUID/ULID Models?

[anhofmann]

Hey, this is a great package, thank you for sharing!
Some of my models are using UUIDs as the id, do you see a way for supporting those in this package?

Thank you for pointing this out!

The logic shouldn't have to change because we're already using the getKey() function on the versioned model - we just need to update the db column to support both types. I'll dig into this some more and get a PR created for this.
