POC: Circular annulus support in Imviz

[pllim]

Description

This pull request is to add circular annulus support so we can simplify UI for Simple Aperture Photometry plugin.

This needs:

• Added translator for CircleAnnulusPixelRegion glue-viz/glue-astronomy#90
• Make ROI.move_to() behave consistently and expose it at subset_state level glue-viz/glue#2391

This unblocks:

• Handle aperture photometry when images linked by WCS for advanced cases #2154

Looks nice!
I like very much the idea of adding an explicit button to move subsets. Maybe the icon can differ from the zoom icon? @Jenneh might have ideas here.
I am not sure I understand the behavior of the last button. Is the width always fixed to 5 pixels or is some dragging required?

Is the width always fixed to 5 pixels

Yes, it is currently hardcoded to 5. I am not sure how to make it fancier without writing a full-fledged plugin. I am hoping it won't matter when we can edit compound subset in the future.

After the discussions on 2023-05-10, people are only interested in using Import Data to load region files (#2188), not the other two features (click to center and annulus stamping).
