Bugfix/importerror cumptrapz
SciPy's cumtrapz function has been renamed to cumulative_trapezoid in newer versions.
Added package "packaging" to requirements, in order to decide which import to execute on which SciPy version.
Note: The GitLab-Pipelines passed, but only for Python 3.8 & 3.10. We should change the pipeline to support newer Python version
