using papermill to produce quiz questions

Adapt https://github.com/CFMTech/jupytext_papermill_post to produce muliple versions of the same quiz

[x] fork https://github.com/CFMTech/jupytext_papermill_post and run the example notebook
[x] make a new notebook that solves two equations in two unknowns, where the equation coefficients are replacable parameters (see https://stackabuse.com/solving-systems-of-linear-equations-with-pythons-numpy/)
[x] adapt the new notebook to the layer radiative flux problem where the unknowns are radiative fluxes being emitted by the layers
[x] read about how to use setup.py to install command line tools: https://godatadriven.com/blog/a-practical-guide-to-using-setup-py/
[x] read about how to use click to document command line tools: https://click.palletsprojects.com/en/8.0.x/
[x] use filter-notebook to add and remove notebook cells
[x] add metadata to produce "precision answer" quiz (item 5) following https://github.com/phaustin/eoas-wl/blob/main/md2canvas/examples/demo_quiz/demo.md
[x] write a bash script to produce 10 student and 10 instructor notebooks
[x] move the bash script to python ala generate_notebooks.py (pha)
[x] push the 10 student notebooks to canvas using https://github.com/phaustin/eoas-wl
[ ] push an instructer-commented student file back to the student submission using https://canvasapi.readthedocs.io/en/stable/submission-ref.html?highlight=assignment#canvasapi.submission.Submission.upload_comment
