Cleaning up low volume protrusions

[pentacular]

After subtracting one mesh from another, sometimes there very thin protrusions.

These are legitimate geometry, but not useful in many applications, and increase complexity.

Is there a good way to clean these up?

If they weren't connected, then remove remove_connected_components_of_negligible_size would work, but these are not discrete components.

I considered collapsing very small edges, and then removing very acute corners, but I wonder if there are better approaches?
