GMFX chemical wafare expansion

this addon makes the gas zones from GMFX better and more realistic. this mod does this by doing the following:

1: this mod now includes 4 levels of chemical agents. these are:
A: riot control agents (CS gas)
- white smoke
- blur vision and drains blood slowly over time
- requires a gas mask

B: choking agents (Chlorine gas)
- greenish yellow smoke
- will cause damage and coughing over time
- requires a gas mask
C: Blistering agents (mustard gas)
- yellow smoke
- more deadly than chlorine gas, and still causes coughing
- requires a full NBC suit

D: nerve agents
- invisible
- drain blood quickly
- requires a full CBRN suit

2: adds the following items to the game:
- M651 40mm cs gas grenade
- VOG 25 40mm CS gas grenade
- M72A2 gas genade (US)
- M25A1 gas grenade (US)
- K51 gas grenade (USSR)
- homemade gas bomb (chlorine gas)
- 5 colors of CBRN suit
- cbrn gloves
- cbrn boots
- oxygen tank
- cbrn respirator
- pepperball launcher w cutom ammo

3: adds gas artillery. simple as that, just an artillery shell loaded up with Chlorine gas.

if you would like to see me support this mod further, feel free to dm me on discord @domin8849. (please don't bother bacon, he has nothing to o with this mod other than the original dependency)

(note: the gas clouds are a little off compared to the kill radii. will try to fix this)

(also, im aware of the issues surrounding the CS gas grenades, im devising a solution now)

(bacon has given me permission to use GMFX as a dependency for this mod)
