use unittest.mock instead of mock

Could you please consider to use unittest.mock instead of mock as a fallback? You seem to support older python versions, so you probably cannot really get rid of it completely for now.

At least for 3.8, 3.9 and 3.10 following works for me:

Older python versions were recently removed from the tests matrix, so a PR that uses unittest.mock instead of the mock library should now be feasible.
