Detailed Description

The troubled-cell indicator run on the FD grid to check if the corresponding DG solution is admissible.

The following checks are done in the order they are listed:

if grmhd::ValenciaDivClean::Tags::VariablesNeededFixing is true then we remain on FD. (Note: this could be relaxed in the future if we need to allow switching from FD to DG in the atmosphere and the current approach isn't working.)
apply the Persson TCI to \(\tilde{D}\) and \(\tilde{\tau}\)
