Python 3.10 has moved abstract base classes from collections to collections.abc available since Python 3.3. This has broken pyxb and, therefore, imports for authorizenet/sdk-python.

There has been a pyxb pull request pending for nearly 3 years that would likely fix this specific problem, but the pyxb author has indicated that the project is at end-of-life without funding or transfer of ownership.

It seems the path to supporting Python 3.10 would involve either:

1. Replace pyxb in the authorizenet/sdk-python project
2. Work with the pyxb author to get that project up to date

Any chance of supporting Python 3.10 in the near future?
