Allow rejecting certain phone number types

[dwightwatson]

This extends the custom validation rule to allow you to specifically block certain phone number types, instead of just allowing certain types.

(new Phone)->type(PhoneNumberType::MOBILE);
(new Phone)->notType(PhoneNumberType::MOBILE);

In some scenarios it makes more sense to block incompatible types rather than allow all the other possibilities.

I like the idea of adding this - it makes sense. I'm wondering though if we should warn the developer if both are used, because only one will actually take effect (the whitelisted ones).

(new Phone)->type(...)->notType(...)

Fair call - I've added a custom exception. See if you're happy with the naming/implementation.

Thanks!
