Reduced Captum Insights package size (#562)

Summary:
This commit reduces the size of Captum Insights by

- Replacing the old graphing library with a more lightweight one
- In the standalone app, using compression in the Flask server
- In the notebook extension, excluding unused dependencies-of-dependencies

![Graph screenshot](https://user-images.githubusercontent.com/13208038/102558400-31c74080-4082-11eb-93b2-9b5c474fa0ae.png)

For the standalone app, it reduces the size significantly:

![size comparison](https://user-images.githubusercontent.com/13208038/102558239-de54f280-4081-11eb-9718-24b9174d408b.png)

For the notebook extension, there's a similar size reduction of `index.js` from 1090 KB to 449 KB.

Testing: I used `titanic.py` to test this change, making sure that the graphs are working as before and that the other functionality is unnafected.
