Add chardet to requirements.txt

[DavidSchinazi]

This does seem to fix things for me. Otherwise I get this:

During handling of the above exception, another exception occurred:

So requests imports charset-normalizer, which is the chardet successor (and superior in many ways). What you appear to be struggling with is a failure of the pip installer, which helpfully picked up an x86_64 version of the package for your armv8 machine. Does make clean-deps help at all?

Huh. I tried in a fresh checkout and I no longer have the problem. The weird bit is that this initially also happened in another fresh checkout, so this wasn't a case of me copying the folder between Macs. Let's close this for now, I can reopen if I see the issue again.

Mark had some issues very much like this. I wonder whether there aren't some issues in terms of how pip manages its dependency resolution.
