[enhacement] Getting country codes/names of proxy

[LeMoussel]

It would be interesting to resolve IPs proxies to country codes/names.
To do this, we can use a free service such as

• ip2c.org.
• ip-api. Their API Batch processing is interesting. My preference.
• ipgeo.
• ipwhois. API is free for up to 10,000 requests per month.

Example ip2c:
https://ip2c.org/1.0.205.8
Result:
1;TH;THA;Thailand

Example ipwhois:
https://ipwhois.app/json/1.0.205.8
Result:
