Plot angle vs z

Add plots of angles vs z in cryodrgn analyze

Probably could be cleaned up - like, this probably crashes if you do a run without some of the necessary parameters? So probably need to check that the params exist and skip if not.

Also not clear if we want to dump these png files vs putting this in the notebook?

From a user's point of view: why not both? I like having the umap plots as png files for quick inspection, but I also like having them in the notebook for when I use the notebook. I also like being able to visualize as many things as possible (very useful to understand a dataset), and coming up with my own visualization is mostly a distraction (I am not very proficient with Python or coding in general) that I would rather skip so I can focus on understanding what the data is telling.
Disk space is abundant for those equipped for cryoEM data analysis, and these files are small.

I suspect this hacky version is going to have too many bugs and will need to be rewritten in a more robust way.
