Map system

Would be cool to add (opt-in) first-class support for agents being positioned in physical space. Then Agents would be able to, say, listen just for events in an N-cell radius, and the Game could render based on what agents are at what positions. This needs some thought, probably informed by trying to make a 2D game.

This idea needs to be revamped and probably more tightly built into the core of the engine: https://cohost.org/nic-hartley/post/3394802-are-you-telling-me-a

Thinking on this further I think the game world thing is separate from this. Map will be an object that helps you build, specifically, a world map, which can be stored in your world state and implements Attachment for easy rendering. It might also offer some functionality to locate events on the map and filter received events by location.
