Summary
These unions were introduced in Python 3.10 and do not define
__origin__
,so some extra checks are necessary to identify then. Since there is not
yet a 3.10 build, a somewhat hacky test was added to simulate one of
these new Unions.
Resolves #414.
Test Plan
Existing + new unittests. Also tested locally in an environment supporting new Unions.
