Type hints from annotations are not correct since python 3.10 #93

Correctly reading annotations change a lot in 3.10. The intent is to simplify things but our code does need to be adapted.
the best practice is now to use inspect.get_annotations(eval_str=True) to get the de-stringified annotations.
Still things need to be checked concerning inheritance behaviours.
