[Feature Request] Support IP2Location.io API

[ip2location-com]

I would like to introduce the IP2Location.io IP geolocation API. It has the following advantages compare to other API providers.

• Fast - one of the fastest API in the market using multi-location servers and Anycast routing
• Accurate - based on IP2Location and IP2Proxy database which is available since 2002
• Free - free tier with 30,000 queries monthly available to all users who sign-up online

Please consider IP2Location.io as one of the database source in ip2geo. Feel free to ping me if you have any questions. Thank you.
