Add Callnumber and VolumeEnumeration to generate_digital_object_json for ILS source

[martinlovell]

The callNumber and volumeEnumeration are needed for the digital object json with ILS source only.

The updates to the MARC records are dependent on the callNumber and volumeEnumeration for ILS records. Include those two fields when generating the JSON for digital objects that are send to Metadata Cloud. (volumeEnumeration is often blank.)

• [x] When generating the digital object json for records with ILS source, add callNumber and volumeEnumeration fields
• [x] Don't add them if the source is ArchivesSpace. Updating the json would cause aspace digital objects to be resent.
