Add retry method for iTunes API requests

[shiibe]

Hi! It's me again 😅

This PR just adds an enhancement to my last one. This will attempt to hit the iTunes API up to 3 times if it fails before falling back to MusicBrainz for artwork.

I'm still trying to get to the bottom of why the iTunes API will sometimes return "Service Unavailable", but after some tests it does seem to go through on the second attempt each time it happens.

Apologies for all of the commits, I had a hard time getting my fork up to date. 😓

Is it something that happens often, or is the iTunes API just struggling from time to time?

I use this at work (listening 6-8 hours a day) and it happens ~5-10 times. The immediate fallback to MB works fine, but it's always nice to have the actual data from iTunes. I've been testing this for a few days now, and every time it's successfully grabbed the data from the API on the second attempt.

I'm still trying to get to the bottom of what's causing the error on the API side of things when I have time.
