Feature Request: Gracefully handle audiobooks that have been manually deleted

[photown]

1. Download an audiobook through qBittorrent
2. After successful download it's placed in the media directory
3. Manually delete the file from Audiobookshelf
4. ReadMeABook gets in a broken state:

• When I search for the same audiobook and open it, its status is shown as "Processing" indefinitely
• When I go to "My Requests" and open the audiobook, its status is shown as "Downloaded"

It would make sense to add an option to clear all cache about an audiobook so that you can easily restart the download if something goes wrong (e.g. if the user accidentally set the wrong path for it).

same for me. I deleted a book because it downloaded the wrong version of it. It still writes its in my library.

Running into this today. A book that was originally processed by RMAB glitched out leaving most of the file muted. I had to remove it from ABS manually but now RMAB is stuck in "Processing" the request. There needs to be a way to gracefully or manually re-process downloaded items.

The only thing I can do to get around this is to manually import the file directly into ABS, skipping RMAB entirely.
