ZK API: can include album art?

[bufordsharkley]

This is related to the music dept project to automate the production of printable templates for reviews, such as follows:

At present, the ZK API includes all relevant information (including track times, thanks to the recent update!), but the album art, while often present, is not part of the API payload (manually copying into a vector editor isn't much work, but full automation is the goal)

(This is related to the previous request to import album art even in cases that Discogs import does not include it: #431)

To clarify, the desired payload is a link to the album art URL, not an embedded binary blob
