Add state/province to the geoip dictionary

**Is your feature request related to a problem? Please describe.**
Currently, the geoip dictionary only has "continent", "country", and "city" that can be used for filtering. It would be great "state" or "province" can be added as well.

**Describe the solution you'd like**
Add "states" or "provinces" to the dictionary.

**Describe alternatives you've considered**
Listing all of the municipalities in a state in the expression policy. This is not very practical, as municipalities in different states can share the same name, and the rule would also be excessively large.
