alternative conversion support

• https://www.willus.com/k2pdfopt/
• comic resizing
  • KCC - maintainability issues
  • https://github.com/avalonv/reCBZ - modern, and can also target webp for readers that support that
  • https://github.com/clach04/comic-book-tools documents other tools
• ocr https://github.com/HaoZeke/Dotfiles/blob/master/dotfiles/common/.local/bin/fileHelpers/isOcr

For example, libraries below have limited conversion support:

• https://github.com/clach04/KindleUnpack fork of https://github.com/kevinhendricks/KindleUnpack
  • https://github.com/kevinhendricks/KindleUnpack/issues/33 setup.py
  • https://github.com/iscc/mobi (py 3.7+ library version available on pypi)
  • work command line ebook reader handles Azw via https://github.com/wustho/epy/tree/master/src/epy_reader/tools/KindleUnpack
• https://github.com/ludios/unbook - looks promising (almost) anything to self-contained html file with embedded images
• https://github.com/aerkalov/ebooklib/blob/master/samples/04_markdown_parse/epub2markdown.py
• https://github.com/gujiaxi/convert-ebook (currently relies on Kindlegen exe)
• PanDoc (could be used for some simple conversions of text only (i.e. skip images) - doesn't do a good of converting formatted books into plain text. But does a decent job of markdown/html into epub including images (and TOC)
  • Epub2md https://gist.github.com/probonopd/68c97814ffb70b627b457d62fbd2b9db
  • TODO doc issues seen https://github.com/clach04/webook_server/issues/2#issuecomment-1261770907
• https://github.com/psiegman/epublib supports html to epub conversion
• my old https://github.com/clach04/html2fb which includes any2fb - limited though
• https://github.com/clach04/pyrite-publisher can emit (non formatted, no images/photos/bitmaps) that both Kindle and KoReader support.
• https://github.com/rupor-github/fb2converter - go
• https://github.com/rupor-github/fb2mobi - python and KindleGen exe

mobi/KindleUnpack appears to offer a way to get epub from azw3 and mobi.

Amazon kindlegen (x86 only) can generate mobi from epub.

Tested with soft reader, untested resultant books on hardware/koreader.

pandoc 2.7.3 does a terrible job of converting my two test epub books into Markdown (lots of junk and zero handling of <span class="TX-ital"> where TX-ital in CSS applies italics). TODO test newer version (currently 2.18)

https://github.com/clach04/pyrite-publisher seems to work for KoReader and Kindle but does NOT offer any form of styling/linking/formatting.
