feat(balance): second revert of shotgun ammo AoE

[RoyalFox2140]

Purpose of change (The Why)

AoE ammo was added without checking damage or arpen. This means Doofenshmirtz managed to add his death in a can inator to destroy THE ENTIRE TRI-STATE AREA!

This is a huge problem because AoE always hits every target inside the cone for full damage and arpen without any aiming or weapon skill involved and can easily clear out dozens of enemies. The worst offender is 40mm rounds that can immediately annihilate most enemies even within mods and do that in a massive AoE.

Describe the solution (The How)

Reverts the AoE on buckshot, flechette, and scrap shot from, but keeps it on bird shot, rat shot, and cannon shells, also dragons breath / pyrotechnic ammo. Also reverts weird damage changes.

A later PR will bring more shotshell types that will add AoE. That's out of scope here, and that's Robbie's work.

Describe alternatives you've considered

Forcing Chaos or Kheir to make shots blocked by targets so it doesn't propogate forever because I can't do that myself. Full nerf of AoE shells because of the associated bugs. Having a form of AoE that splits into projectiles so buckshot is actually 8 smaller rounds that hit within the cone.

Testing

It'll load.

1. You made 20ga paper shot equal in damage to regular 12 gauge. I'd suggest having 12 gauge be 50 and 20ga be 40.
2. If you're going to nerf damage, you NEED to check for other ammotypes that inherit from ammo you changed. This nerfs the everloving shit out of slugs for example.
3. You forgot .410. 30 is good I guess awawa

[RoyalFox2140]

410 was nerfed in the previous PR, but the rest ill have to look at

Aight. I hate to do this but to be honest this code still really has needed more time in the oven for years at this point, stupid problems with it just keep coming up.
