Unable to install on Python 3.10

[Federico-PizarroBejarano]

Hello,

I have been using pytope for several years, but recently found that I can no longer install it. I am unsure why. Here are the steps to reproduce the issue:

conda create -n test python=3.10
conda activate test
python -m pip install pytope

I get the error:

This does not happen for Python 3.8. I would really appreciate help with this as it is interfering with our open-source gym utiasDSL/safe-control-gym#167. Thank you!!

Hmm it seems to be an issue with a recent update of pycddlib. I think by setting an earlier version of this dependency this issue can by bypassed.
