Fix Ruff identified issues for catalog/marc files

[hornc]

Closes #7886

• Condenses down the get_subjects from MARC code so that it is easier to read and understand what is being extracted and placed into the various subject type categories.
• Passes the Ruff complexity test
• Removes a method and regex to do with 'Aspects' -- unsure what this was for. Undocumented, untested, and the str return value of the function were never used anywhere. Appears to be something that was never fully implemented?
• Removes some duplication with org subjects, and places appearing duplicated as general subjects or organisations. Tests expectations have been modified to remove the duplicates.
• More specific exception handling in Binary MARC
