Backport "ExceptionGroup" classes from Python 3.11 to Python 3.7-3.10

Python 3.11 has updates that Python versions 3.7-3.10 do not have by default. But this can easily be remedied by using https://pypi.org/project/exceptiongroup/ (ExceptionGroup)

This will improve backward-compatibility for those who are still using older versions of Python.
