I ended up not caring about configurability for now. The country vs
country code thing is fairly easy, that can be done with some
command-line parsing. Using a different database is harder, as right
now, I open the database on module load.

With a @declare, it's easy to make the database configurable, but only
globally: you wouldn't be able to use multiple databases. I'm not sure
whether that's a problem or not. Nevertheless, it is something I don't
want to deal with right now.

The result is currently sitting on my feature/3.4/template-func/geoip
branch, but I will likely merge it into merge-queue/3.4 once I added
command-line parsing.
