Heroku Buildpack: GeoLite2 GeoIP data

This is an unofficial Heroku buildpack that installs the latest GeoLite2 City and Country free IP geolocation databases from MaxMind along with the libmaxminddb C library for fast lookups in the databases.

Note an older version of the Country database is available in any Heroku deploy via the packages geoip-bin, geoip-database, and libgeoip1 listed on https://devcenter.heroku.com/articles/stack-packages

As of 30-Dev-2019, Maxmind has withdrawn unauthenticated downloads of their free GeoLite2 databases. Read more here.

From Jan-2020 users need a Maxmind account, and a valid license key. This buildpack uses the "direct download" method described in the Maxmind developer documentation (https://dev.maxmind.com/geoip/geoipupdate/#Direct_Downloads).

In order to download the Maxmind databases, you will need a valid Maxmind license (register with Maxmind and click on "My License Key" in the left-hand menu). You must add this key as an environment variable (setting) called MAXMIND_LICENSE_KEY.
