Connected component

Li-Ta Lo requested to merge ollielo/vtk-m:connected_component into master

This is an update on the Connected Component support in VTKm. It contains the following changes

  1. Corrected a concurrent algorithm error on the UnionFind for the ImageConnectivity which gave erroneous connected component identifications for density fields for MFIX particle data.
  2. Added filters for both CellSetsConnectivity and ImageConnectivity.
  3. Added unit tests for aforementioned filters.

CI looks good to me except on seemly spurious error on the Timer that most likely due to heavy workload on the test machine.
