Orchid looks for Tor's geoip database (IPv4 address ranges to country codes,
used for the {cc} entries of node filters) as data/geoip in the working
directory, among other places; see CountryCodeService.

It is not part of Orchid.  Get it with ../tools/update-geoip.sh, or install
Tor's (on Debian and Ubuntu: apt install tor-geoipdb).

Tor makes the file from the IPFire Location database
(https://location.ipfire.org/), which is licensed under CC BY-SA 4.0.
