*Description edited by @RemiLehe *

This adds support for electron impact ionization, within the DSMC module.

Note: could we do binary charge exchange in the same way?

TODO:

  • Use the proper energy cost: store the energy cost in the SplitAndScatter functor
  • Avoid creating a particle of the neutral species
  • Add support for excitation in DSMC (right now, it prevents us from running the capacitive discharge test)
  • Test on GPU
  • Add a dedicated CI test for DSMC ionization. Note: for now, setting very high tolerances on purpose. This needs to be modified once all features are implemented in the PR.
