Libation trying to download books that are not released yet

[Tamba3998]

Describe the bug
Audible Japan recently(?) added a feature where you can "preorder" audiobooks that will get released with the flatrate plan at a future date.
These audiobooks get picked up by Libation, but fail when you try to download them (because they are not released yet).
All of these titles have a "date pub'd" in the future in the misc column, and it's possible to filter them out with a search like
datepublished:[20000101 to 20241214]

To Reproduce

1. Go to https://www.audible.co.jp/coming-soon and add any of the audiobooks with the orange button to your library. I'm assuming the same will happen with the regular preorders (the magenta buttons that are also available on the other region's Audible), but I have not tried it
2. Try to download them. The download will fail with the error "Book has no codec specified"

Expected behavior
Libation should ignore those books because the download can never work

Platform
Linux (EndeavourOS)

Log Files
The only relevant part in the log files is this error (which makes sense because it's trying to download something that is not released yet):
System.ApplicationException: Book has no codec specified. Cannot continue with download.

Thank you for reporting this since it is a legit bug in relation to this new feature. I have no access to a .jp account so I'm not able to do anything about it right now. I'll leave this ticket open so it doesn't get lost.

As a bandaid: when your book does become available, if it has an error in Libation, you should be able to right-click > download to force Libation to attempt to download it again.

Just wanted to add that this happened to me as well, but in the US and on MacOS. It occurred with Amorph by Chene Lawson and N.K. Jemisin and Hitchhikers by Ben H. Winters.
