Deprecation warning due to missing pyproject.toml

[GeeTransit]

I'm following the installation instructions for Windows and there's a deprecation warning when installing from source:

Building wheels for collected packages: PyOgg
  DEPRECATION: Building 'PyOgg' 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 'PyOgg'. Discussion can be found at https://github.com/pypa/pip/issues/6334

The fix seems to be simple (see: pypa/pip#6334), just add a pyproject.toml with the following contents:

[build-system]
requires = ["setuptools >= 42.0.0"]
build-backend = "setuptools.build_meta"

I tested this change locally on Windows and the warning no longer appears when I uninstall and reinstall PyOgg. Didn't seem to break anything on Linux either (can't test macOS).

Also side note but the warning does not appear if I don't pip install wheel. Not sure why that's the case.
