Support A1, A2 special countries

[urusha]

It would be nice if we could build database with A1 (Anonymous Proxy), A2 (Satellite Provider) special countries support.
Currently, this hack of editing csv inside zip could be used (country example):

echo '12000001,en,--,"",A1,"Anonymous Proxy",0
12000002,en,--,"",A2,"Satellite Provider",0' >> GeoIP2-Country-Locations-en.csv

sed -i 's/^\(.*\),,\([0-9]*,[0-9]*,1,0\)$/\1,12000001,\2/; s/^\(.*\),,\([0-9]*,[0-9]*,0,1\)$/\1,12000002,\2/;' GeoIP2-Country-Blocks-IPv4.csv GeoIP2-Country-Blocks-IPv6.csv
