Tag all subclasses of "release" with "music release type" or it's subclasses (https://w.wiki/3ezC) + also manually add missing formats/types from p7937 of every p31:album/ep/compilation (https://w.wiki/3eTX etc).

Also make a hierarchy:
music release type / music release format (separate if necessary)

• album type
• digital media format
• gramophone record format
• multi-disc album format
• physical media format
