It looks like the simple-salesforce version requirements on the requests library were recently bumped to >=2.22 whereas this plugin requires ==2.20.

Compare:

• https://github.com/simple-salesforce/simple-salesforce/blob/master/setup.py#L29
• https://gitlab.com/meltano/tap-salesforce/-/blob/master/setup.py#L13

This is causing execution to fail at runtime.
