Add support for UUIDs

[floodedcodeboy]

Great work on this project, just one gripe however. It doesn't support UUIDs. Having support for this would be awesome! and also make it even more compatible with spatie roles and permissions.

Not clear enough.
As per what I understand, for UUIDs you are free to configure uuids in your database tables instead of integers. The package utilizes Spatie's Permissions package. So you should be able add UUIDs without a problem.
