Allow passing `callingCode` to the `formatIncompletePhoneNumber`

Could we please make it possible to not only be able to pass a country code, but also a calling code to the formatIncompletePhoneNumber function?

Instead of:

formatIncompletePhoneNumber(number: string, countryCode?: CountryCode): string;

... we would have:

formatIncompletePhoneNumber(number: string, countryCode?: CountryCode | { country?: CountryCode, callingCode?: string }): string;
