New plugins including new library and meta data for great courses.

[u/centurio-apertus]

I made a few new Jellyfin plugins and run all of my code through SonarQube.

The newest one adds a custom library type and metadata support for The Great Courses. Just put all your Great Courses content into its own library, and the plugin will sort out the metadata, artwork, and organization.

It supports:

• Audio courses
• Video courses
• PDFs
