[WYD] Primitive Prosthetics

Allows crafting of peg arms, and hook hands.

A simple add-on that just allows one to give pawns immobile wooden arm replacements, given that the prosthetic arm is way up in the research tree. I understand that the prosthetic limbs unlocked there represent modern replacement appendages, but more basic limb replacement has been around forever - not just peg legs.

Anyway, this mod adds:

Peg arms: I went with "peg" to correspond with the in game "peg leg" but essentially this is a non-jointed wooded arm. Not much for manipulation, but an improvement on lacking an arm entirely.

Hook Hand: Because pirates. But yeah replacing the hand in its entirety wasn't really a common thing, and unless you are someone like Jaime Lannister and can easily afford to splash out on overpriced luxury, a simple metal hook would have sufficed, and been both lighter and cheaper.

ATM the hook component is just a lump of steel to keep it in check with the "peg" surgury options. If I decide to expand on this mod at a later date* then I will probably set it up as an actual item and add an unlock to the smithy technology. I may even add a few extras in such an event, but it is not a priority.

*really, I just made this coz some asshat stabbed one of my zero-tech playthrough pawns through the arm, and apparently that either destroyed it, or it was cut off in healing, and I'm not waiting forever to get some value out of him
