Added all three ipyvolume slices within a single plot, each with an attached slider to control the selected slice.
Testing
[ ] Run build.sh and make sure new dependencies install in .venv
[ ] Open up the notebook (make sure using the .venv Python kernel)
[ ] Execute the first cell, and ensure that the all three slices show up beneath the ipyvolume graph, and each of the sliders updates the corresponding graph.
Closes #178
