Feature request: Cities names in rulesets

[nmr50]

Hello dear author !

Could you please add feature to use SECOND database on MaxMind - named as CITY ? What I am talking about. As you surely know Russia is a BIG country, and sometimes I need to specify what cities/region should have access to specific page or not.

For example, CITY database (in .csv) has such record - 524894,en,EU,Europe,RU,Russia,MOW,Moscow,,,,,Europe/Moscow,0 So I can use "RU-MOW" to specify access only from Russia, Moscow, and its nearest small cities. Or 498817,en,EU,Europe,RU,Russia,SPE,St.-Petersburg,,,"St Petersburg",,Europe/Moscow,0 I can use "RU-SPE" to access only from Russia, St.-Petersburg, and its nearest small cities...

Maxmind CITY db is located here: https://geolite.maxmind.com/download/geoip/database/GeoLite2-City-CSV.zip https://geolite.maxmind.com/download/geoip/database/GeoLite2-City.tar.gz

Thanks in advance !
