Clean up comparison notebooks and fix vis.py

[amystamile-usgs]

When cleaning up the comparison notebooks, incorporating the newer ALE implementation essentially standardized the code across all the comparison notebooks. Therefore, I decided it would be more efficient to maintain a single comparison notebook.

closes #108, closes #92, closes #123

I also noticed that vis.py dependencies were not being shipped in the knoten releases (kalasiris and plotly).

Ohh also, kalasiris dependency - can that be optional? Honestly, can all of the vis stuff be optional? For someone not wanting to do a comparison, they are bloat in a CSM library.

Maybe not including vis.py dependencies was intentional. I think it would be a good idea not to ship kalasiris with knoten. I can just add instructions to install it in the notebook.

LGTM!
