To generate new geoip files, you'll need to install the
libloc/"location" tool provided by https://location.ipfire.org/.
I personally build it with:

./configure CFLAGS='-g -O2' --disable-perl --without-systemd --prefix=/opt/libloc
make
make install

Then (after adjusting PATH and PYTHONPATH) you can get the latest
dump with:

location update
location dump geoip-dump.txt

And transform it into geoip files with

cargo run --release -- -i geoip-dump.txt


==============================

Note that the current version "0.1.9" of rangemap has a performance
bug, making this tool quite slow. Previous versions had a
correctness bug that made the output needlessly long. With luck,
there will soon be a fast correct rangemap version.
