Fixed Wanderwand Deselect. (#293)

* Fixed bounding box comperison

This caused unitended errors resulting in no-zero intersections when they should be empty.

* Optimised Wanderwand

Added selection merge to selection deletion, preventing NBT crashes from boundingboxes splitting repeateadly, without ever being merged.
