[FEATURE] Remove watched media data and requests

[RLoris]

Hi again,

This is another feature request, I think this would help a lot of users, it is related to watched content in jellyfin, decluttarr could track watched state and trigger a removal of the media data + request after a specified period of time, this is to allow torrents to seed and then make some disk space for new medias requests. It would query watched date of a media currently tracked by sonarr/radarr and then if watched, once ADDITIONAL_TIME has passed, delete it and remove it from sonarr/radarr. I haven't found something that matches this behavior with jellyfin/jellyseer, and I think media cleanup falls into declutarr mission of "removes downloads if they become stalled or no longer needed."

What do you think about it, is it something that could be implemented ?

Many thanks for this amazing tool !
