FEMA camp jsonify

Summary

SUMMARY: Content "FEMA camp jsonify"

Purpose of change

Continuation of hardcode-to-json mapgen conversion.

Describe the solution

Extensively used nested mapgen. The whole location is a compilation of previous hardcoded mapgen, jsonified mapgen of FEMA camp from #34081, and lots of my own additions here and there.
There are 4 variants of lodging (communal and individual tents), 2 variants of sanitary facilities (toilets/showers/medical station), 1 variant of corpse pit, 3 variants of mess hall, 2 variants of supply storages, 1 variant of entry, and 1 variant of lab.
I significantly increased number of monsters in the location as it felt like there were too few of them for such a big camp.
I added two searchlights (with a plutonium generator to power it) and sandbag barricades to the entry.
Removed all mentions of hardcoded FEMA camp (as well as earlier jsonified hazardous waste sarcophagus) mapgen.

Describe alternatives you've considered

None.

Testing

Debug-spawned the location many times to see if everything is ok.

Shouldn't some of the zombies that spawn in the corpse pit have been from body burning(presumably by those flamethrower zombies in the screenshot) and thus be scorched, like they are at the military base's corpse pit?

Added chance to spawn scorched zombies.
