There seems to be some issues with mypy typing. Could you please recommend what's the best way to fix it?

[VMRuiz]

I added some exceptions in tests code for mypy errors because I couldn't make them work in the class definition itself.
Also, there is another error about a licence in twine pipeline

[wRAR]

The twine problem is global and should be fixed by bumping the deps in twinecheck

I guess docs will make more sense once we actually implement a location parameter for spiders.
