KindleGen is no longer available for download

1. https://www.amazon.com/gp/feature.html?docId=1000765211 says "KindleGen is no longer available for download."
2. All old download links from http://kindlegen.s3.amazonaws.com now give access denied

See #363 (comment) for possible workarounds.

Upstream issue: tdtds/kindlegen#42, though I doubt anything can be done here.

I have opened a support case with Amazon to see if something can be done. Not much faith, but who knows...

After some calls and couple of mails I just got a dismissive "thanks for your feedback and using Amazon products. We will pass those suggerences to the development team". 🤷‍♂️
I am afaid we are quite out of options.
