Download episode art along with audio

[idkwebdev]

Sorry for the cross-posting. I originally put this under feature requests in Discussions, but it seems like it's not getting much attention there. Plus, I think this is better characterized under "Polish".

Problem:
When a podcast is automatically downloaded, Pocket Casts does not download the episode art. Instead, it uses a placeholder image.

Expected Behavior:
I should be able to view the episode art offline without having to manually open the episode and load the artwork.
