Feat: Passage Map 🚢 (#3304)

## Description:
Introduces Passage, an island filled thin map (like Amazon River but
inverted) which is a long, thin stretch of islands that makes for some
really fun gameplay. I playtested with 3 friends a number of times and
it's great in pretty much all the modes. Naval gameplay on this map is
particularly fun since some islands in the center basically hold the
choke points on trade ships passing from one side to another, making
them hotly contested territory.
