Moving Annotations

[azmathmoosa]

This is an excellent tool with lots of useful features. One of the things it is really missing is the ability to move annotations once they are made.

Particularly, the mask annotation using Brush/Polygon once made, cannot be moved. Is it possible to create a new tool called "Move" whose only job is to be able to select and move an annotation. Be it BBox, Polygon, Mask or Keypoint.

There are many cases where copy annotation feature is used to copy annotations to next image. But if the object has moved slightly in the next image, one has to reannotate it. It would be a lot easier to just move the annotation.

Does this feature already exist? If not, which source files can I explore to implement this and submit a PR if possible.
