Handle multiplicity of points in visualization

[sauln]

Currently, the visualization does not indicate whether there are points being overplotted.

We could possibly:

• Add jitter (this could be confusing as it would change the interpretation of the diagrams).
• Make points opaque so multiple points are easy to see.
• Add annotations indicating multiplicity.

Yes this issue came up during the Italy workshop actually. My vote would be annotations for multiplicity greater than 1 if it happens. Also, perhaps we should create an alternative plot for persistence bars also, where this issue doesn't occur

I would also like annotations, but I think they could easily become overcrowded.

As a quick solution, I make some changes to the defaults so they are slightly opaque and have a border. This makes it a little easier to see multiplicity.
