Setup metadata needs to be re-written, otherwise build will break from 2023-11 on.

With python 3.11, I get some big fat warnings which prompt that you have to re-structure your setup metadata, otherwise it will fail to work in the future:

* Getting build dependencies for wheel...
/usr/lib/python3.11/site-packages/setuptools/dist.py:754: SetuptoolsDeprecationWarning: Invalid dash-separated options
!!

        ********************************************************************************
        Usage of dash-separated 'description-file' will not be supported in future
        versions. Please use the underscore name 'description_file' instead.

        By 2023-Sep-26, you need to update your project and remove deprecated calls
        or your builds will no longer be supported.

        See https://setuptools.pypa.io/en/latest/userguide/declarative_config.html for details.

        ********************************************************************************
        The license_file parameter is deprecated, use license_files instead.

        By 2023-Oct-30, you need to update your project and remove deprecated calls
        or your builds will no longer be supported.

/usr/lib/python3.11/site-packages/setuptools/command/build_py.py:201: _Warning: Package 'openpyn.management' is absent from the `packages` configuration.
!!

        ********************************************************************************
        ############################
        # Package would be ignored #
        ############################
        Python recognizes 'openpyn.management' as an importable package[^1],
        but it is absent from setuptools' `packages` configuration.

        This leads to an ambiguous overall configuration. If you want to distribute this
        package, please make sure that 'openpyn.management' is explicitly added
        to the `packages` configuration field.

        Alternatively, you can also rely on setuptools' discovery methods
        (for example by using `find_namespace_packages(...)`/`find_namespace:`
        instead of `find_packages(...)`/`find:`).

        You can read more about "package discovery" on setuptools documentation page:

        - https://setuptools.pypa.io/en/latest/userguide/package_discovery.html

        If you don't want 'openpyn.management' to be distributed and are
        already explicitly excluding 'openpyn.management' via
        `find_namespace_packages(...)/find_namespace` or `find_packages(...)/find`,
        you can try to use `exclude_package_data`, or `include-package-data=False` in
        combination with a more fine grained `package-data` configuration.

        You can read more about "package data files" on setuptools documentation page:

        - https://setuptools.pypa.io/en/latest/userguide/datafiles.html


        [^1]: For Python, any directory (with suitable naming) can be imported,
              even if it does not contain any `.py` files.
              On the other hand, currently there is no concept of package data
              directory, all directories are treated like packages.

@jotyGill if you're around, please look at recent issues.
