Migration Failure Fix

What's New

• PDF uploads as a source, which can be updated via a reconfigure or service.
• Local PDF uploads, which will be polled for updates.
• Better error handling, including offering repairs. The current version of home assistant offers limited repairs but hope that a future version will support better repair handling for subentries.

Bug fix

• Unfortunately it's too complicated to migrate the configuration. You'll need to delete your configuration and recreate it to support these new entities.
