Steps to reproduce the bug

Open a Bandcamp album containing as many tracks as possible, but not more than 9 tracks.

Actual behaviour

NewPipe queries BandcampPlaylistStreamInfoItemExtractor.getThumbnailUrl() for every single track as soon as the album is opened before any part of the album is displayed.

Expected behavior

Because this method call needs to do an additional web query for each track for Bandcamp, the call should be executed together with the query that downloads the cover art, i.e. it should display the rest of the album with placeholder images while the call is being executed.

More info

Currently, a workaround is implemented to avoid long loading times for large albums: when there are at least 10 tracks in a playlist, each stream in the playlist is displayed as having the same cover art (code).
