Using a formatter and editing linting/formatting rules

[vandyliu]

Description:

Using a formatter to make our code look more clean: prettier for typescript and black for python. The code stylings were quite inconsistent and there were many linting errors (and still are), but hopefully using formatters can help us with our code quality. Also, the formatting checks will be added to CI if this is merged. All the src code files that are changed were changed by the formatters.

New commands:
npm run lint
npm run check
npm run format

Cool! I would just suggest adding the commands for formatting in the documentation.
