Inspired by Bundle as Quiver by boyonk.
Extremely similar functionality; no copied code; all was written by me.
Follows typical projectile priority order, but if a bundle is encountered, it will be searched for a projectile, and if the bundles are layered, the same will happen to them, assuming no valid projectiles were found. This should work with any modded projectile weapons that use ammo, along in addition to bows and crossbows.
Monsters do not gain the ability to spawn with bundles, but if they have one with a projectile in it for whatever reason, it will be searched for a valid one rather than automatically using a default arrow.
