Remove legacy setup.py bdist_wheel mechanism

[mwetter]

Building BuildingsPy on travis yields

Building wheels for collected packages: buildingspy
  DEPRECATION: Building 'buildingspy' using the legacy setup.py bdist_wheel mechanism, which will be removed in a future version. pip 25.3 will enforce this behaviour change. A possible replacement is to use the standardized build interface by setting the `--use-pep517` option, (possibly combined with `--no-build-isolation`), or adding a `pyproject.toml` file to the source tree of 'buildingspy'. Discussion can be found at https://github.com/pypa/pip/issues/6334
  Building wheel for buildingspy (setup.py): started
  Building wheel for buildingspy (setup.py): finished with status 'done'

This issue is to update the configuration to avoid this warning.
