This simple mod removes bullet tracers 
Inspired by this mod - No Tracers https://www.gta5-mods.com/weapons/no_tracers

Original Mod changed: <TracerFx>Bullet_Tracer</TracerFx> to <TracerFx></TracerFx>.
Edited to:            <TracerFx>Bullet_Tracer</TracerFx> to <TracerFx />

I suspect the engine understands it better this way.
Did the same to the DLC weapons.

Original mod only edited vanilla weapons.
DLC weapons were a bit tedious to find but here they are.
Find any not working properly, let me know.
