Restrict to 1 annotation per canvas.

[NLW-paulm]

Is it possible to restrict Madoc to only allowing one annotation per canvas? This annotation can be edited, but there is only one annotation. We have an edge case where a user wants a single authorative record per canvas, although people can edit and add too that single annotation. This would allow them to export one annotation per canvas with all the information they need.

Note - as an enhancement, there will be a cost to this, please let us know what this might be and I can pass it onto people involved.

To be clear, this should be a config option per site or capture model.
