Add explicit dependencies on matplotlib, scipy
Description
I noticed that although various notebooks use matplotlib & scipy, we weren't actually declaring them as dependencies. I've taken the versions already installed on max-exfl016 (in /home/xcal/calibration_webservice_venv), so it shouldn't change anything immediately. But if we recreate the environment, we'll get the same specific versions again rather than whatever other dependencies pull in.
There are more packages installed on max-exfl016 which aren't in setup.py - these were only the ones that I noticed were used directly from this project.
How Has This Been Tested?
We already run with these versions in production.
