Covasim tutorials on Binder fail on sciris import

[edwenger]

Binder-hosted covasim tutorials fails on sciris import (specifically some deprecated matplotlib.colors function calls from sc_colors.py)

Looks as if pip install sciris==2.0.3 (instead of 2.02, which the tutorial loads by default) is the fix.

Thanks @edwenger , will get this fixed today!

Fixed -- bumping the version in requirements.txt seemed to trigger a cache clear for Binder.
