Data update: Typing for 3 Letter country code #174

Data changes

Right now, the typing for 3 letter codes are awkward:

import countries3to2 from 'countries-list/minimal/countries.3to2.min.json';

function convert(threeCode: keyof typeof countries3to2): string {
    return countries3to2[threeCode];
}

If we can get one of the below, the typing would be a lot less awkward:

• an internal, typed function that does countries3to2 conversion
• a typed list of 3 codes
