Boundary smoothing

[mrbuche]

Is your feature request related to a problem? Please describe.

None of our dualization plans will change the fact that exterior and interior boundaries will still be stair-stepped.

Describe the solution you'd like

An interior (possibly exterior) surface smoothing scheme is required, possibly something like marching cubes?

Describe alternatives you've considered

Dualization of the segmentation will mostly place cells-as-voxels along boundaries, which will become elements, which will leave us with approximately the same stair-stepped boundary as if we directly meshed the segmentation (in comparison, the only new thing we can is interior adaptivity).

Additional context

This might be more important in the short term.

It also could be useful to just have the option to return the reconstructed surfaces as STL etc. files.
