Clean command - remove only orhaned directories

[prullenbak]

Hi, maybe this is a feature request, but I don't know if it's already possible. It might even be something that I could contribute, if necessary. Anyway, the question:

is it possible to let the media-library:clean artisan command remove only "orphaned directories" and not "deprecated conversions"? We convert some media types (video) seperately from the built in ones, because we need a different format/resolution of video's after they have been uploaded. So in short:

• a user uploads a video, laravel-medialibrary creates a thumbnail
• we listen to tehe conversioncompleted event and then convert and transcode the video on our own, storing it in the conversions folder.

Now, when we run the media-library:clean command, it sees all those conversions as deprecated conversion. This is logical, but a bit incorrect. So it would be very nice if we could tell the command to leave those conversions alone, and only remove the "orphaned directories".

Thanks!
