adds map of the Caucasus (#3661)

## Description:

Adds map of the Caucasus. This map is made especifically because of the
new update that allows ports to be placed on smaller bodies of water,
rather than just the largest one.

This map has 2 disconnected, large bodies of water of similar size
(Black and Caspian seas), which would create 2 independent trade
systems, creating a more dynamic economy.
