Add a drug lab

[MNG-cataclysm]

Summary

Content "Add a drug lab"

Purpose of change

Add a drug lab, as we do not have a stationary drug lab that can spawn outside of cities.

Describe the solution

Add a drug lab, based off of the moonshine stills' layout, Zombies can spawn there, and it contains meth, chemicals, and lab equipment.

Describe alternatives you've considered

Making multiple drug labs dedicated to one kind of drug, such as one for weed, meth, opioids, etc.

Testing

Spawned the drug lab, went to it, killed the inhabitants, and died to a meth overdose.

Additional context

Jessee, if you're reading this, we need to cook.

Interesting. It seems it tends to spawn with random chemicals?

From what I can tell the "methlab" itemgroup also throws in some topical items.
I couldn't manage to find where that item group is actually defined though.

I noticed you mentioned making drug-specifc drug labs as an alternative. I overall agree that seperate maps for drug types probably isn't necessary.
Although, I do think having some variance built into a single map is a good idea though.
The simplest way I can think of would be to have the same map. But, have multiple loot tables flavored to a particular drug type. Then have it pick which one to use at certain rates.

Although, even adding just one in is interesting.

Maybe adding a "drug stash" item group to the loot tables might be a good idea?

Game loads without errors, not seeing any mapgen errors either.

Just about the only "large scale" suggestion I have is that this misses a roof.
I'd also recommend replacing place_monsters with place_monster in case the dice roll the wrong way. Also, having hazmat zombies spawning here instead of ordinary ones would stop children or dogs from spawning here.

We do, but it's just very rare #28958
