fix: Implement guide-based cover image fallback (#830)

This partially fixes #769 but is dependent upon PR #827 being merged along side this @daveallie. I removed my PNG conversion code after finding out that PR was already created. Without this PR though that book in #769 will still fail to load because of how it's stored in the file --------- Co-authored-by: Dave Allie <dave@daveallie.com>
