September, 14th: readibility improvements

These Cookbook improvements were made available by 13 contributors since last release, in March.

Thanks to @johanwiden (a first time contributor, even), the EPUB and PDF got great readability improvements:

• the EPUB can be read in Emacs' nov.el reader
• internal links now work
• tables where changed from markdown to html tables
• many fixes while generating the EPUB
• more typos and grammar fixes

Moreover:

• files and directories:
  • added how to set the current working directory with UIOP
  • new "Create pathname components" section
• scripting:
  • build a standalone binary with Deploy (and handle foreign libraries such as libssl, deal with ASDF etc)
  • mention SBCL 2.2.6 zstd core compression gains
• getting started: mention rlwrap -c trick to autocomplete file names
• iteration: mention iterate's in-sequence
• Emacs: better example of Emacs' C-u M-( command
• web: improve Systemd section
• add favicon
• fixed an example that was using load instead of asdf:load-asd
• a missing Lem screenshot to show it in action as a Lisp REPL in the terminal was added:

You can pay what you want for the Common Lisp Cookbook on ko-fi.
