Country name for every phone number

[IT-Tool]

Would be nice to see the country name of every phone number stored in contact card (to automatically determine the name of the country by the first digits of the number). List of country calling codes can be taken from here (for example):

• https://en.wikipedia.org/wiki/List_of_country_calling_codes
• https://www.countrycode.org/

Also will be useful to sort/filter contacts by country or city.
