Not compatible with python 3.10

[depuits]

When running the code using python 3.10 you get the following error

AttributeError: module 'collections' has no attribute 'Sequence'

Traceback (most recent call last):

I sent an upstream patch to the valideer team to fix their code base. podio/valideer#28

It would seem that the valideer project is dead. The last update is from 2018 and merge requests don't seem to get merged. I'm guessing the only real solution will be to remove the project from the dependencies and replace the code. As far as I see it is only used for the validation of the input arguments. Couldn't that be replaced using some type checks and regex without the need of a third party library?

Yes, I think that makes sense (although I really like their interface...). Anyone volunteering?
