Fix this:
GeoLite2-Country-CSV_20180905$ /usr/lib/xtables-addons/xt_geoip_build
Use of uninitialized value $dir in concatenation (.) or string at
/usr/lib/xtables-addons/xt_geoip_build line 59.
Couldn't open list country names
Do not rely on any directory names (they change). Use the current
directory as the default source directory, similar to the older
xt_geoip_build (well, *.csv was passed as arguments).
Add a tool for retrieiving the IPv4 or IPv6 (or both!) CIDR ranges
for a given country, which can then be injected into an ipset if
one doesn't want to use (or have available) the xt_geoip extension.

Requires Net::CIDR::Lite for manipulating CIDR blocks, aggregation, etc.
since database is stored as subnet/mask pairs and may require compaction
into ranges (which can combine adjacent subnets).
We don't use Net::CIDR because it's a clunkier interface.

This allows a single database to be built and distributed as a
package that is accepted by both big- and little-endian hosts.
