DQM output format and parsing script

[jlenain]

This PR introduces a new format for the DQM output in FITS files, as well as a user script which, once a DQM analysis has been run on DIRAC, grabs the results from DIRAC, extracts the archive and ingests the results in the ZODB data base.

This is a fundamental brick towards an automatic pipeline which would launch the DQM systematically on DIRAC on data transfer from CEA to DIRAC, and results ingestion in ZODB.

This was tested to run fine locally (see http://lpnhe-cta2.in2p3.fr/nectarcam-dqm), but we need to merge this PR, to trigger the building of an Apptainer image in CI, which would then be used to launch a couple of DQM jobs on DIRAC, to be able to further test the user script from start to finish.

In case of issues along the way, another PR will be opened.
