Using phonenumbers library this module adds tools methods as well as a
small mixin for models that want to activate phone number validation
and formatting.
Formatting can be done always using an international format or having
both national and international format. This is configured on the
company.
Note that phonenumbers library is optional. Installing this module without
having the lib installed just skip its use but should not crash.
