Manim: ValueTracker must support increment also using +=

[nilaybhatia]

Just what the title says. Here's an example

class Test(Scene):
    def construct(self):
        tracker = ValueTracker(0.0)
        tracker.set_value(2.0)
        print(tracker.get_value()) # -> 2.000
        tracker.increment_value(3.0)
        print(tracker.get_value()) # -> 5.000
        tracker += 4.0 # NEW proposed feature
        print(tracker.get_value()) # -> 9.000

Very good idea. I would love to see a PR :) #

Hey, @huguesdevimeux I can take this if it's still open.

Hi @SamMinkowicz,
We all appreciate your willingness to help the Manim Community out, but unfortunately I already started working on it and just opened a PR a minute ago before seeing your comment. You can still help us out by maybe giving suggestions on that PR :)
