Downloading should not be based on PRO.CATG, but on the class name so you can search for any data product, also RAW or static calibrations

Currently it is possible only possible to do these two queries:

        if pro_catg:
            results = (Pro.pro_catg == pro_catg)
        else:
            results = DataItem.select_all()

but that doesn't make much sense. If you query on a pro_catg, say LINEARITY_2RG, then you should do:

results = LINEARITY_2RG.select_all()

because then you can also query for raws etc, like

results = IFU_SCI_RAW.select_all()
