Phony 2.1 incompatibility related to country codes/numbers

[pjg]

In phony_validator, in the common case, a country code is passed to the Phony.plausible? method:

@record.errors.add(attribute, error_message) if not Phony.plausible?(value, cc: country_code_or_country_number)

While Phony expects cc to be specifically a country number, otherwise the phone number will not be plausible.

Phony.plausible?('+1 555 1234 123', cc: 'US')
=> false

Phony.plausible?('+1 555 1234 123', cc: '1')
=> true

The solution is to do the ISO3166::Country::Data conversion from country code to country number.

I'll try to create a PR for that this week.
