[Sky Island] Add possibility of autodocs or CBMs to Exodii crash pods

[Standing-Storm]

Summary

Mods "[Sky Island] Add possibility of autodocs or CBMs to Exodii crash pods"

Purpose of change

When Sky Island was created, you could still find autodocs in bionic basements, and you could still find autodocs and CBMs in some doctors' offices. Both of these are now gone, greatly restricting the chance of finding CBMs and autodocs out in the world.

But, Exodii crash pods would be a good place to put them. They're something you have to prepare to break into, they're things the Exodii would reasonably be transporting, and then you're encouraged to antagonize the non-zombie Exodii if you want to steal their tech.

Describe the solution

Add a version of nest_exodii_crash_building_big_2 that has an autodoc and couch in it.

Add lootgroups for low value, medium value, and high value CBMs, and add them to the Exodii loot groups SUS_exodii_storage_lowvalue, SUS_exodii_storage_medvalue, and SUS_exodii_storage_highvalue. This doesn't guarantee CBM loot, but there's a chance.

If you can break into those vaults.

Describe alternatives you've considered

Testing

Autodoc pod:

CBMs aren't super common compared to raw materials, but you can find them if you're lucky.

Additional context

Unless I'm misunderstanding something, your new nest_exodii_crash_building_big_2 mapgen chunk isn't spawning anywhere?

It's one of the possible nests picked for the crash mapgen:
