PySide6 (Qt for Python) and Shiboken6

Used by the optional tray app `naneos-gui` (`pip install "naneos-devices[gui]"`). Not needed by
the library, the `naneos-uploader` command or the Raspberry Pi installation, and not included in
the naneos-devices package: it is installed as the separate PyPI packages `PySide6-Essentials`
and `shiboken6`, from the Qt Company, unmodified.

License declared by both packages (version 6.11.2, checked when this file was written):

    LGPL-3.0-only OR GPL-2.0-only OR GPL-3.0-only

naneos-devices uses PySide6 under the GNU Lesser General Public License, version 3 (LGPLv3).
Because the package is installed on its own and imported dynamically, you can replace it with
another version of PySide6 (one that meets the requirement in pyproject.toml) at any time.
