No Extension handling

[MB34]

Libphonenumber offers handling of extensions using the x1234 or ext.1234 format. Can you add that, please?

Also, how would I write a function to return my Local format number broken into the parts? I'm only doing US numbers so it would be CountryCode, AreaCode and Number, plus the extension, if you add it.

This is a pretty big one I feel.
