What kind of RoomVisual support do we want?

Opening this as a separate issue from #30 since there are multiple ways we could support this and discussing it seems fairly self contained.

RoomVisual allows drawing nice graphics on rooms. It's a convenient API. However, all of the JS code in RoomVisual does is create the right JSON structures then call console.addVisual(room_name, structure).

In implementing bindings for RoomVisual, we could either wrap RoomVisual's methods themselves, or just wrap console.addVisual and create a RoomVisual equivalent ourselves in pure rust code.

The latter seems to make more sense. It'd greatly reduce the overhead of communicating through the screeps API.

I'm curious however: would we bypass this restriction

However, there is a usage limit: you cannot post more than 500 KB of serialized data per one room (see getSize method).

I don't believe we would - the check is done in addVisual itself rather than in any of the wrapper methods: https://github.com/screeps/engine/blob/551aa41163c45273d706ce238c6b35f379c0149e/src/game/console.js#L40

Here's a PR for the full API: #306
