The `MeshQuality` filter only worked with `CellSetExplicit<>`. However, `MeshQuality` should also work with `CellSetSingleType`. Fix `MeshQuality` to work with both. The handling of cell sets was actually worse than that. After forcing the type to `CellSetExplicit<>`, it then applied a policy that converted the types back to all possible cell sets. Thus, the filter made lots of code paths that were impossible to follow.
