add countryCode number to the intitialCountry

[rbalet]

What
Beeing able to give a number instead of an string into the ng2TellInputOptions.

[ng2TelInputOptions]="{ initialCountry:  41}"

Why
I become countryCode (ex: 41) frome the db, which doesn't save the countryName (ex: ch) and want to initialise the flag with this number

How
I think, using te geoIpLookup from intl-tel-input could be an idea, they user the initialCountry: "auto", and then, instead of the geoIpLookup we could use our own function that look for the countryName.

intl-tel-input

intlTelInput(input, {
  initialCountry: "auto",
  geoIpLookup: function(success, failure) {
    $.get("https://ipinfo.io", function() {}, "jsonp").always(function(resp) {
      var countryCode = (resp && resp.country) ? resp.country : "";
      success(countryCode);
    });
  },
});
