Add option to exclude chosen albums from fetching cover art

Hi, thank you for your work on this component, I've been using it for years.

I think it'd be beneficial for there to be a feature that lets you exclude certain albums from fetching cover art. Many albums have NSFW covers and the Cover Art Archive does not disallow them, so I'd be worried about listening to an album that has an NSFW cover and inadvertently displaying it on my Discord profile, which would probably put my account at risk.
