As mentioned in #301, the current implementation of MaxMindBinaryProvider is far from perfect. This is mostly because of the geoip/geoip package we use under the hood.

Obviously there is a newer lib, named geoip2/geoip2, which would be better. I'd like to switch to this package, but it would imply a BC break, so I suggest the introduction of a new provider (GeoIP2Provider? MaxMindBinary2Provider?) leveraging the geoip2/geoip2 lib. Also, we should mark MaxMindBinaryProvider as deprecated.

WDYT?
