Python 3.10 breaks build via pip

[jkitchin]

I am moderately sure that Python 3.10 breaks the install.

With This Dockerfile the install works fine:

FROM jupyter/scipy-notebook:python-3.9

RUN pip install gryffin    

But with this one, it does not build

FROM jupyter/scipy-notebook:python-3.10

RUN pip install gryffin

and gives a long set of errors that starts and ends with

I don't have a solution. It looks like a known issue with 3.10, e.g.https://bugs.python.org/msg393401 and https://bugs.python.org/issue43760.
