[Paraview] DigitalRockPhysics Plugin Usage

[Mathieu Westphal]

Dear Michael

CellDataToPointData is interpolating at the points, so the results is
incorrect because of all these small interpolated cluster.

In any case, Explode should work with CellData as well, this is definitelly
a bug. I've opened an issue on our gitlab.
https://gitlab.kitware.com/paraview/paraview/issues/18108

A work around this bug would be to generate point data directly without
interpolation.
