Subject: [PATCH] docs: install from the repository, not a nonexistent PyPI
 package

pycube-lut is not published on PyPI (pypi.org/pypi/pycube-lut/json returns 404), so
the README's pip install pycube-lut and pycube-lut[hald] extras commands cannot
work. Replace both with the git+https install form, matching what the
headlessmode site already publishes for this tool. Verified the hald extra
exists in pyproject.toml and both install forms succeed in throwaway venvs.
