Use Type Checker like mypy to check the type annotations.

[dsr20030703]

Description of proposed feature

I’ve found some type annotation errors in manim. For example, the argument color of FadeToColor expected str, which should actually be ParsableManimColor.

As there may be also other type annotation errors, I suggest using type checkers like mypy to check type annotations.

How can the new feature be used?

This helps ensure that you’re using variables and functions in your code correctly. Plus, it would benefit other Python projects using type checkers to import manim.
