Fix the requirements

[monocongo]

When I attempted to install dependencies via pip install -r requiremts.txt into a fresh conda environment (Python 3.10.4) I received the following error message:

$ pip install -r requirements.txt 
ERROR: Could not find a version that satisfies the requirement ertifi==2020.4.5.1 (from versions: none)
ERROR: No matching distribution found for ertifi==2020.4.5.1

A reasonable fix is probably to update the requirements.in file and run it through pip-compile to produce a correct requirements.txt.
