Use (Oi)FITS keywords to highligh SCI or CAL targets

[gmella]

Is your feature request related to a problem? Please describe.
Retrieving long list from external tools may show SCI or CAL targets. Nothing is present to highlight science data?

Describe the solution you'd like
We would like to get a way to sort all of them visually from SCI to CAL category.

A first way could be to add in the label the category in parenthesis. If the target have SCI and CAL oifits it's tree item label could be :
HD1234 (SCI&CAL)
else
HD234 (SCI)
HD345 (CAL)

Describe alternatives you've considered
I have no workaround to make this highlight possible in the same application.

Rules have to be specified to make such categorization on top of fits keywords. Last implemented for SPICA was :

if HIERARCH.PRO.SCIENCE=T -> SCIENCE
if HIERARCH.PRO.SCIENCE=F-> CALIB
