Weapon weight diversity

Give every weapon a weight stat that acts as a small modifier to movement speed when a weapon is held. LMGs, behemoth, c-tac, and genesis being among the heavier options that slightly reduce player speed when held.
Rifles having the more default speed with little/no deviation in weight.
And SMGs/Pistols being the lightest, having a positive modifier on player speed.

This would allow for more weapon diversity and an opportunity to give SMGs and Pistols stronger identities/usecases, especially for SMGs currently outclassed by other options. While also leaving room for LMGs to be reworked to be stronger, while requiring a player be slowed down into a role of suppression and support.
