Optimization to avoid allocating a supercell site mask when it is all true. This includes a runtime check for the cases where it is not evident from the type of supercell inputs. As a result supercell is no longer type-stable. However, this instability allows unitcell to become faster while remaining type-stable, because it no longer has to check mask to build the list of sites.
