Extend automatic segmentation CLI to continue annotation

[anwai98]

I came across a random thought: would it be interesting to integrate annotators to automatic segmentation CLI?

This would go in the direction of an intuitive segmentation workflow, where: user utilizes the CLI to perform automatic segmentation, and can move ahead with parsing an argument stating --annotator, which will activate the napari GUI, load the automatic segmentation to the committed_objects and a user then has the choice of improving segmentation using interactive mode.

PS. I also feel it might be an overkill, it's just a thought though (only makes sense if it's beneficial for a use-case).

I think that's a nice idea, and not much overhead. Before this we should make sure the segmentation_result argument works correctly in all annotators, as this would be how to implement this.
