Feature Request: Archipelago support

[ketsuban]

Archipelago (GitHub) is a "multiworld multi-game randomizer" - it randomises multiple games together such that any game in a set can contain items and unlocks for any other game in the set. A single player can play through all the games one at a time, or multiple players can play different games at the same time.

La-Mulana would be an excellent addition to this project, and there's already some amount of support for Java-based randomisers for Slay the Spire and Minecraft.
