Provide an accurate list of required packages

[qbojj]

We should provide a curated list of required packages with their supported versions.

It may be good to also provide a reproducible build environment.

• Nix flake to consider?

Wasn't this solved by #66 and #78 ? What other information do we need?

[qbojj]

Yes, although the build environment was not included - could be separate issue

Also packages required to build documentation are not mentioned anywhere (or at least I couldn't find them). What was missing for me: doxygen, python-sphinx, python-breathe, python-pydata-sphinx-theme.
