feat: add country code of external IP address

This commit adds functionality to retrieve the country code of the external IP address. If the country code is not already stored in a file, it uses curl to fetch it from https://ipapi.co/country and saves it in "${tmpdir}/countrycode.txt". If curl fails, an error message is displayed.
