add Baja California map 🏜️ (#3759)

## Description:

Adds map of the Baja California peninsula in Mexico. Majority of this
map is brown terrain to simulate the (Sonora) desert
Mexican and American states as NPCs. The peninsula while having little
landmass is balanced by the fact it will be very easy to pirate from it
