Add Python 3.10 support & update dependencies

[juhoinkinen]

This changes CI/CD tests to be run on Python 3.8-3.10 instead on 3.7-3.9 and updates mentions of Python version support to 3.8+. Wiki may still need updates for this.

Also

• upgrades pinned dependencies to newest available (except for simplemma as there is some breaking change), which is now possible since dropping Python 3.7 support
• switches to use importlib of the standard library, previously the 3rd party package was needed for Python 3.7
• verifies installed packages have compatible dependencies using pip check

Compatibility of models trained with older dependencies should still be checked and documented.

Closes #589.

Merge commit for resolving conflicts due to #587.

I run evaluation of just released Finto AI models with the upgraded dependencies: Models work with the usual warnings by sk-learn (e.g. Trying to unpickle estimator CountVectorizer from version 1.0.2 when using version 1.1.1. This might lead to breaking code or invalid results.) and evaluation results change just slightly for some data-sets.

New releases of connexion and NumPy were made just yesterday, so I upgraded them now again.

Simplemma v0.7.0 includes a breaking change, and I'm not sure how that should be fixed (can the simplemma.load_data() be just dropped?), so simplemma is left pinned to v0.6.*.

I can fix the simplemma issue!

I think current master (with the flake8 fix, #598) should be merged to this PR branch and if everything still works, it can be merged to master.
