Adds more "curated" version of human randomization (for humonkeys, corpse spawners, and fresh characters) (#84443)

## About The Pull Request

Basically, adds a version of `randomize_human` that's a tad more
curated, IE, primarily picks results to create a more "coherent" result
than full randomization.

Shown here: Humans, Lizards, Felinids. Looks a bit boring, but that's
the point.

Non-humans I left almost entirely untouched, as they generally form a
more "coherent" mob from pure randomization already.

## Why It's Good For The Game

Basically just aiming to perform a more "consistent" style for humonkeys
and corpses.
For monkeys, it doesn't make the most sense when they pop up with a
giant red afro.
For corpses, it's a bit hard to feel immersed in the ruins when they've
all got pink and green mustaches.
