storing graphics in dict

[clewis7]

addresses #64

moved to store graphics in dict with keys as the graphic class

keys currently need to passed in as a string, need to work on implementation to allow for

gp[0,0].get_graphics()[ImageGraphic]

as opposed to

gp[0,0].get_graphics()["ImageGraphic"]

[clewis7]

right now, I have it creating the keys to the dict by

self._graphics[graphic.__class__.__name__] = list()
self._graphics[graphic.__class__.__name__].append(graphic)

but __name__ returns a string, any suggestions on how to get graphic class name not as a string when just __class__ gives fastplotlib.graphics.image.ImageGraphic

yea not sure whether the best approach is to have it as a str or the class type itself, I think using graphic.__class__ should work, you can check if:

graphic.__class__ is ImageGraphic

after this is done modify the __repr__ for PlotArea such that if there are > 5 graphics of any type, show only the first 5 and last 5 because I know there will be someone at the workshop who crashes their jupyter because they ended up calling the repr while having 10,000 graphics in a gridplot 🙃

after #88 there is now a class attribute that stores the name of the graphic as a str in lower case, see: https://github.com/kushalkolar/fastplotlib/pull/88/files#diff-a57994ecff1cde4e05c8175265219f0b5200da144ce8733b9eb560c09bcea7ddR9

rebase on mater or just start a new PR, this is pretty straight forward.

I think that since PlotAreas are indexable we don't really need this. We can revisit if it becomes necessary in the future.
