Merge branch 'develop' into feat-media-availability-sync-emby/jellyfin-support

This refactors the media availability job to support jellyfin/emby for media removal automatically.
Needs further testing on 4k items (as I have not yet tested with 4k), however, non-4k items work as
intended.

fix #406, fix #193, fix #516, fix #362, fix #84
