American Express cards are invalid #44

A typical credit card number (i.e. Mastercard) looks like this:
5555 5555 5555 4444
and an American Express card looks like
3782 822463 10005

Using the Default CardNumberFormatter, American Express cards are invalid. Can we get some sort of formatter that can be used with both?

Hi @anthonycastelli!

Should be possible to have an algorithm that supports all types.
