Ports (or, well, tries to) "Undersized" quirk from Doppler

[epicgamer545]

About The Pull Request

This ports over the undersized quirk from Doppler, reworks it to be compatible with Iris's code, and also ports all of it's PRs, including:

• Adds the Undersized Quirk DopplerShift13/DopplerShift#400
• Let undersized carp genemods function as slightly more powerful wirecutters when picked up DopplerShift13/DopplerShift#414 (lol??)
• Tiny update DopplerShift13/DopplerShift#427
• Undersized Examine and ID code DopplerShift13/DopplerShift#431
• Makes undersized people no longer be squashed by non-dense objects, no more tram slidealong hell DopplerShift13/DopplerShift#746

This is all (mostly) modular.

Why it's Good for the Game

It's a fun quirk and I can see it being used for character customization in creative ways. Also, it's balanced (and when I mean balanced -- you can be stepped on, you can be picked up, your grabs cannot be upgraded into lethal, using guns flings you, etc)

Proof of Testing

It compiled. I want to see if this passes checks though They passed. Somehow.

here is a complimentary video (sorry for bad quality)

update: the port on NovaSector/NovaSector#6484 (nova's end) is still stale and i expect it to be stale for a long time. idk what we could do if it gets merged but i assume they'll literally just be the same stuff i did (or maybe more, in that case we can merge them both)
