Center the selected object, and add some additional zoom presets.

**Is your feature request related to a problem? Please describe.**
For object detection labeling, there is a review stage, to ensure if model-assisted annotations are fine. If not, apply corrections.
But I am dealing with very small objects (mostly around 20-40 pixels), zoom-100% is still very small, and to draw a conclusion I need to manually zoom a few more times each and every one of them.

**Describe the solution you'd like**
When I select an object from left side list, It would be great if it auto-centers that object, instead of cycling among the detections across the image. Also, you may add additional zoom presets like 200% and 300%, this both helps a lot for reviewing the smaller objects. This way, I can use keyboard arrow buttons up and down to navigate in the list, to individually inspect each of auto-labelled objects, at a desired zoom scale.
