If anyone wants to build this, i'll merge it in.

@bluesmoon As far as I can tell continent is not directly available in any of the Maxmind geoip databases.

But I did find this mapping provided by Maxmind from ISO 3166 country code to continent code: https://dev.maxmind.com/geoip/legacy/codes/country_continent/

(It appears the mapping is also included statically in the C library implementation: https://github.com/maxmind/geoip-api-c/blob/a16267aec08fe9e9f7875b8d8b2f3d2cc154e51e/libGeoIP/GeoIP.c#L542)

So what I'd like to do is use the Maxmind country code->continent mapping and perform lookups based on that. I can point it to the download on the above Maxmind site. I don't think it's necessary to process the simple lookup table into .dat format, so I'd just keep it as CSV or maybe convert it to a json map that can be loaded in directly from data/. Let me know what you think.

Sure, go ahead. I would have preferred if there were a separate library to map country to continent since it seems like something usable outside of geo-ip as well, but if there isn't then this is fine.

My concern with any kind of continent mapping is the complication with Turkey which is simultaneously in Asia and Europe or countries like France or the Netherlands which are primarily in Europe, but also have portions in the Caribbean and elsewhere.
