Zoom Deactivation

Nobody has claimed this yet.

## Description of the proposed feature
The feature I want to propose is a zoom deactivation system
It would look like this.
```python
from manim import *
class Basic(ZoomedScene):
def construct(self):
self.activate_zooming(animate=False)

self.deactivate_zooming(animate=False)

```

I would like to do this because we can activated zooming but not deactivate it.

## How can the new feature be used?
In cases where you would like to zoom in for a little bit but then remove the zoom.

Start by tracing ZoomedScene and the existing activate_zooming entry point to understand how zoom state is created and managed. Add the proposed deactivate_zooming behavior and verify it with the example sequence in the issue, including deactivation without animation.
