Hey @anatoli-ulmer
I am not conviced that #5 was a top-shot for two reasons: first, manually downloading will fail unless you install in developer mode, and even then, its a pain. second, the downloaded data isnt even used at all. I think this is the point where we should start code reviews with one another before merging.

Thanks for spotting the bug fixed c59c37d. Next time, maybe you can add to the commit message, that functools.cache was introduced in python 3.9. So its easier to understand why this is a bug.

How do we proceed with the downloads? I would just revert 47b020f and 998b99c for now as they do not add to functionality.
