[Feature Request] Include Alt Kindle EPUB Fix in available CLI tools

[tzw9373]

Is your feature request related to a problem? Please describe.
Send to Kindle often fails due to pickiness on epub formatting, https://github.com/TheWox/kindle-epub-fix is the most reliable tool that I've encountered to correct this issue.

Describe the solution you'd like
Include this tool as an available option in CLI or GUI tools to easily correct formatting issues and resend to Kindle quickly.

Describe alternatives you've considered
Converting an epub to another epub can sometimes correct the offending formatting, but not always.

Additional context

The original version of this tool has already been rewritten in python and added to the next release. It is already available in the dev build but currently only for ingested and converted epubs, manual triggering of the script is currently being added
