[ReveredRedHood]

Introduction
Add events related to picking up objects to carry them (not putting items in your inventory, but instead holding them in front of you), dropping them, and throwing them.

Description of the feature

OnItemPhysicsPickUp(Interactable) // controller.MoveablePickUpThis()
OnItemPhysicsDrop(Interactable) // InteractionController.Instance.carryingObject.DropThis(bool throwThis)
OnItemPhysicsThrow(Interactable) // InteractionController.Instance.carryingObject.DropThis(bool throwThis)
Lib.Player.DropCarriedItem => InteractionController.Instance.carryingObject.DropThis(false)
Lib.Player.ThrowCarriedItem => InteractionController.Instance.carryingObject.DropThis(true)
