CalibrationLevel - mapping to ObsCore

[mcdittmar]

The description says this is the enumeration of different possible calibration status of the property as defined by ObsCore.

ObsCore-1.* defines calib_level as an enumerated integer {0,1,2,3,4}.
The definitions in ObsCore Section 3.3.2 match for the first 3, the last 2 are not represented { Raw=0, Instrumental=1, Calibrated=2, =3, =4 }

This model needs to do something since ObsCore is not a VODML model. I think it should match the full ObsCore descriptions, where the number is significant, and the name is the ‘label’. If MANGO PhysicalProperty.calibrationLevel needs to restrict this to (0,1,2) only, it should do so at the attribute and state that the others do not apply in this context.

There is nos a vocabulary for this. The document refer to it now

I like the migration to a vocabulary.. some comments:

1. this is a draft vocabulary, so tying MANGO to it would require the vocabulary to be approved along with the standard. That's fine, I'm just not sure what state that vocabulary is in.
2. MANGO should use the base URL (http://www.ivoa.net/rdf/processing-level) rather than the resolved (https://www.ivoa.net/rdf/processing-level/2024-11-12/processing-level.html)
3. Section 7.1.1 has no 'type' for the attribute. (became NULL with removal of CalibrationLevel I presume)
4. Section 7.2 section heading for CalibrationLevel still exists
