Grabs the text of the book UNSONG by Scott Alexander from unsongbook.com and makes an epub out of it.
Requires Python 3 and PIL. Creates a folder cache which caches the downloaded text and images so it can be re-run again later and be a lot quicker. Requires Calibre's ebook-convert to actually do the conversion to epub.
Run bash create_unsong_book.sh, which will output Unsong.epub.
