Crash on comicvine parsing during library import: ValueError invalid literal

[abartov]

Description of the bug

Attempting to import a small library, Kapowarr silently crashes (the browser hangs). The logs show this stack, which I interpret to mean a parsing bug on the Comicvine output:

Expected behaviour

Import should succeed. If there's an error, it should report it clearly to the user (not everyone is technical enough to view and understand the stacktrace), and continue with the next file.
