Work around build errors due to incomplete pyproject.toml

[matthiasdiener]

For recent setuptools versions, the pyproject.toml file appears to override setup.py, such that some dependencies will not be installed, leading to a missing pybind11 dependency.

Another option might be to replicate the dependencies in pyproject.toml, but it needs a way to specify a dependency for the (local) aksetup_helper module, which may not be possible (see https://github.com/pypa/setuptools/discussions/2951).

$ python -m pip install -e . -v

  Very likely, the build process after this message will fail.

  Simply press Ctrl+C and type
  python -m pip install pybind11
  to fix this. If you don't, the build will continue
  in a few seconds.

$ python -m pip install pybind11

$ rm pyproject.toml

$ python -m pip install -e . -v
[works normally]

How about #110 instead?

Closing in favor of #110.
