Alt PKA balance pass (#5253)

## About The Pull Request
Tweaks the alt-PKA damage values to accomodate for the fact some of them
fire in special ways, or fire more projectiles

The shockwave is now no longer able to fit any variant of an AOE mod, to
stop people from one-shotting everything,

The shotgun damage has been reduced as well, making up for the fact it
fires three shots.

Comments have been added for the existing variants explaining the
reasoning for their current damage level.

Adds a new var for restricted MOD types, allowing for other pkas having
this added in the future.
## Why It's Good For The Game
It is not fun for other miners when someone three shots a boss they
havent even had a chance to think about yet.
