Issue NASA-AMMOS#199 - Upgrade to Python 3.10

Because of the strictly pinned versions this library would only work with
Python 3.7, as stated in the documentation. Since the dependencies are well
founded they provide support for newer versions of Python, including Python
3.10. By migrating to the newer versions this library will now support
Python3.10 but drop support for other versions.

Nose is no longer maintained and does not support 3.9+. This commit
removes nose as a dependency in favor of pytest.

Fixes NASA-AMMOS#199
