kernel::delete_faces(body, faces): Delete Face with healing. The body is rebuilt from its own topology: faces away from the gap stay, planar neighbours keep their other edges, loops that ran along deleted faces (hole rims, boss footprints) go, corners on the gap move to where the neighbouring planes meet across it, and the gap closes with straight edges. Fillets, chamfers, through and blind holes and bosses come off exactly; curved neighbours and gaps the neighbours cannot close are refused naming the face
