Segfault on Python3.10 when importing klampt 0.9.0

[FlurinArner]

Issue resolved with klampt 0.9.1 (at least since klampt 0.9.1.post5)

In Python 3.10, if klampt version 0.9.0 is installed, loading the library immediately causes a SegFault. Although already resolved, I thought to create an issue (which can be closed immediately as resolved) for future reference if someone encounters the issue again (please let me know if this is undesired).

To resolve, install the newer klampt version with:

• pip install klampt (should get the newest version), or
• by referencing the desired version directly pip install klampt==0.9.1.post5,
• or (if using Poetry) updating the reference in pyproject.toml to:

  [tool.poetry.dependencies]
  klampt = "0.9.1.post5"

This issue can be reproduced by running (note: installing libopengl0 and libgl1-mesa-glx is necessary as detailed in #185):

docker run -dit python:3.10
docker exec -it $(docker ps -ql) bash
apt-get update && apt-get install -y libopengl0 libgl1-mesa-glx
pip install klampt==0.9.0
python -c "import klampt"

Looks like this is fixed.
