More crossbow ammo for regular darts

[Die4Ever]

Enemies with crossbows should also give regular darts?

This one is actually complicated due to the permutations of these conditions being true or false

• player already has weapon
• player does not have the weapon but full inventory
• player has max tranq darts ammo
• player has max regular darts ammo

Maybe a better idea is just to boost ammo counts for bundles of regular darts (and flare darts) in DXRReduceItems. And maybe add a few more of them in DXRFixups, replacing some PlaceholderItems and PlaceholderCrates. Maybe especially in later levels when pistol ammo becomes a bit more scarce.
