From: Stefan Klug <stefan.klug@ideasonboard.com>

Our current theme doesn't handle many of the rst features (namely notes,
proper code highlighting, font formatting). The sphinx book theme
provides a unobtrusive design which makes the documentation way more fun
to read. The branding is minimal. The libcamera logo is included and
theme colors are set to the libcamera blue.

To get meson/sphinx to successfully compile the docs the package
"python3-sphinx-book-theme" needs to be installed (at least on debian
based systems).
