REFACTOR : Removing sounds features (NOT sound added to videos)

By “sound not added to videos” I mean all the sounds feature that used to be played when an animation render was finished. Example, here https://github.com/huguesdevimeux/manim/blob/037c9be804a73915d73106167ff4274f04d39576/manim/__main__.py#L168-L179

            try:
                # By invoking, this renders the full scene
                scene = SceneClass()
                open_file_if_needed(scene.file_writer)
                if sound_on:
                    play_finish_sound() # HERE 
            except Exception:
                print("\n\n")
                traceback.print_exc()
                print("\n\n")
                if sound_on:
                    play_error_sound()

There are countless stuff related in the basecode, and I thinl it should be removed.

I agree, this should be removed.
