Request: Additional IP GeoLocation Providers

Hi,

Currently Zero Spam offers support for IPBase, IPInfo, IPStack for geolocation data, however I’d like to request two other providers:

1. KeyCDN IP Location Finder API which is free for all users, it allows a total of 7.8 million requests per month; throttled to 3 requests per second.
2. ip-api.com which is free for all users, it allows a total of 1.9 million requests per month; thottled to 45 requests per minute

These providers should be able to provide adequate information, are just as up to date as the current providers and are better for the majority of wordpress users/websites given the no-API key requirement.

Thanks
