Hello! This is an awesome tool! Thanks for developing it!

I've noticed that for the podcasts I've been using for quite some time, in 2.4.0, the preview image as well as the episode specific images seem to be lower quality.

I've added the following line, but it doesn't seem to be working for me:

custom = { cover_art_quality = "high" }

Is that syntax correct?

Please note that I am not specifying custom cover art but pulling it in from YouTube.
