### VTK linear-cell contour and edge tables

The compressed linear-cell case and edge tables in
`warp_simdata/operators/_iso_surface_tables.py` are derived from
`Common/DataModel/vtkMarchingCellsContourCases.cxx` at VTK commit
`f761daf6d525755e5fa854791223770f2f257a9e` and the corresponding linear-cell
implementations in that revision. See the
[pinned source file](https://gitlab.kitware.com/vtk/vtk/-/blob/f761daf6d525755e5fa854791223770f2f257a9e/Common/DataModel/vtkMarchingCellsContourCases.cxx).
