TCTracksForecast: NetCDF filter error on Python 3.11

NetCDF throws the following error in climada_petals.hazard.test.test_tc_tracks_forecast.TestECMWF.test_hdf5_io:

E   RuntimeError: NetCDF: Filter error: bad id or parameters or duplicate filter: (variable 'basin', group '/')

See https://github.com/CLIMADA-project/climada_petals/runs/27187449177/ This only occurs on Python 3.11. Unfortunately, the error message is cryptic and does not tell a lot.

It might have to do with compression of variable-length data (basin is probably a string?), which is not supported. According to Unidata/netcdf4-python#1175 (comment), zlib=False might solve the issue.

Will probably be fixed by CLIMADA-project/climada_python#911
