add ibdb.dev as a metadata provider

https://ibdb.dev/ is a book metadata service I set up, backed by https://isbndb.com/

That's amazing! Great work! Only one thing, if you're hosting https://ibdb.dev/, what version of the API is it running on? The free keys only allow 1 request per second and so if all of CWA's users start using this provider in the next version, there will be too many requests for it to handle no?

so I have the basic account, which is 5k requests a day and 1/sec. I cache results, so if multiple people have the same filename, it will only make 1 request to ISBNDb. If it becomes a problem, I can probably do some better searching/culling on the cached data. Also I can proactively fetch a list of books on publication date, so I can fill in a backlog and forelog, and then requery each day, and then do the searching on the cached data, and kick off a live search if there are no or only a few results.
