Feat: Lemnos Map (#2683)

## Description:

Introduces the Greek island, Lemnos, as a map. The island is both fun
and challenging to play (because of the terrain and elevation) and this
addition was inspired by Altis from the game [Arma
3](https://armedassault.fandom.com/wiki/Altis). The nation names are set
based on the real landmarks, towns, and regions.
