c2p: Add option `c2p_set_atmosphere_on_failure`
Adds a new option c2p_set_atmosphere_on_failure
to the GRHD
and SRHD
sections.
If true
and the c2p solver fails to invert the master function, we reset all variables to atmosphere.
We also fixed that the running with verbose
in c2p
no longer resest to atmosphere.
