More work on masks (#607)

* Add a #air mask, the opposite of #existing (#1511)

(cherry picked from commit 84fa2bbbc63de7bece01f41c0d5cb7d85cf129e6)

* Remove unused methods in Mask.java

* Remove `test(Extent, BlockVector3)` from Masks.

This was a poorly planned idea. This should save some memory too.
