`setup.py` [lists Python 3.6-3.9 as supported versions](https://github.com/spdx/tools-python/blob/main/setup.py#L54-L57). However, CircleCI [runs against Python 3.7-3.10](https://github.com/spdx/tools-python/blob/main/.circleci/config.yml#L106-L113). If the latter reflects the current state, `setup.py` should be updated.
