ENH: Add option to Surface Meshing to NOT create triangles that would have Face Labels of 0:0

[imikejackson]

Sometimes when surface meshing having all of the extra triangles that border the virtual box and empty space within the virtual box are not wanted. Having an option to simply NOT create the triangles in the first place would be useful.

Quick Surface Mesh

The combination would be 0:0 for FaceLabels

Surface Nets

The combination would be -1:-1 for FaceLabels. SurfaceNets is probably a heck of a lot more complicated to add this feature into just due to the algorithm itself.

Example of output under this option:

Example of what it looks like currently:
