countryForDial

function countryForDial(digits):
  | Country
  | undefined;

The country a +-prefixed number belongs to.

Ambiguous by construction: +1 covers 25 countries here and there is no way to tell which from the calling code alone. The first table entry for a code wins (the United States for +1, Russia for +7), which is what every phone field does, and the caller can override with country.
