More tinkering, also tried to implement bounce sound effects, but they don't seem to work.
Added a config to disable casings.
Commented out smoke effect because it wasn't working out.
Fixed offset rotation sorta, now casing align with the ejection port for the most part. Turrets still need work in this regard.
Fixed some texture asset names.
FBI shotgunners make spent casings, but they are jank since NPC rotations don't match with their rendered rotation for some reason (ie NPC is facing player when rendered visually, but the actual entity isn't).
