Adds map of the Caribbean 🏴‍☠️

[RickD004]

Description:

Fixes #4069

Adds map of the Caribbean sea and its islands. Archipelago map with lots of islands, lots of water and a lot of trade.

This map has multiple large landmasses of similar size to prevent steamrolls (the largest islands and landmasses are around 30%), and many, many small islands where players can survive and trade. Players will have to island hop in order to win. 34 nations of Caribbean countries and territories, with an extra 28 AdditionalNations for a total of 62 nations for crowded HvN.

Heavy Island maps are very popular in the broader community and we dont have one for v32, so i figured it would be nice to have a very requested and popular world location

570k land tiles, fairly small for a map, would be right placed before World (600k tiles). Also adds some flags of caribbean regions.

Poem

🌊 New isles on the coded sea,
Flags and names in harmony,
Enum set, maps registered true,
Playlists learn a turquoise hue,
Caribbean sails into view 🏝️
