PEP517 deprecation warning on current pip/python versions

[vinceskahan]

pyephem seems to be triggering the (coming) deprecation warning for PEP517 (this example - debian12)

Is this one a known issue in the queue to work hopefully ?

Installing collected packages: ephem, pyephem
  DEPRECATION: pyephem is being installed using the legacy 'setup.py install' method, because it does not have a 'pyproject.toml' and the 'wheel' package is not installed. pip 23.1 will enforce this behaviour change. A possible replacement is to enable the '--use-pep517' option. Discussion can be found at https://github.com/pypa/pip/issues/8559
