Python xviz example not working for python versions >=3.9

[PabloVD-Aerosim]

I'm running the serve_scenarios.py script from the circle example for the python xviz library. It works fine for python versions <=3.8. However, for higher python version, it does not work, it raises an error. Here is the output error using a conda environment with python 3.12:

/home/xviz/python/examples/serve_scenarios.py:52: DeprecationWarning: There is no current event loop
  loop = asyncio.get_event_loop()
Traceback (most recent call last):
  File "/home/xviz/python/examples/serve_scenarios.py", line 53, in <module>
    loop.run_until_complete(server.serve())
                            ^^^^^^^^^^^^^^
  File "/home/tda/miniconda3/envs/py312/lib/python3.12/site-packages/xviz_avs/server/server.py", line 59, in serve
    return websockets.serve(**self._serve_options)
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
TypeError: serve.__init__() missing 1 required positional argument: 'handler'

Any clue on why is that? May I modify something in the serve_scenarios.py script to make it work?

Apparently, this error comes from a modification in the websockets.serve function in websockets +11 versions. I managed to make the xviz example work by downgrading websockets to websockets==10.4. But a proper solution for any websockets version should be better.
