Ground IDs

[hohav]

We should include ground IDs, but the representation needs thought. From @Walnut356 via peppi#62:

I did a quick check of the ground ID's on the tournament legal stages, which I've left in tables below. There's 2 holes in this data: stadium transformations, and the little divots on the walls of yoshi's (though I'm not sure they even have IDs).

Implementation isn't 100% straight forward. Every stage has little areas next to the ledges - sometimes multiple per side - that count as "different ground". We could represent it exactly how it is in the game, or we could just lump them all in under "it's the main stage". If they are lumped, do we lump yoshi's slants in as well? They're the same conceptually, but they affect gameplay way more.

The other option is to just put in both, likely with the generalized one being the default (e.g. ground_id and ground_id_exact).
