Title: Fixes "Delete" voxel behavior

- adds "Exits" bits to packet format that allows us to know when a sub tree doesn't exist in the tree vs just not included in the packet
- handles deleting nodes from the client tree when the client receives a packt with clearly marked "exists bits" that don't match client tree state
