feature idea: allow triggering of hdf5 converter on fits files from within the CARTA filebrowser

When the file browser is opened to look at whether a .fits output file looks sensible and if it does also allow for triggering the hdf5 conversion within CARTA.

There are performance concerns about this feature and potentially this can disrupt a controller-based CARTA server hosting multiple active users. Even with the -s flag (lower memory usage), the conversion may take a while. So it is more sensible to use fits2idia tool for the conversion outside CARTA instead.

Would the two following concepts also disrupt multiple users?

1. Submit a slurm job for each individual .fits to hdf5 conversion (triggered from CARTA).
2. Setup a dedicated .fits to hdf5 converter node which takes care of the resource management and conversion priority.
