Flint: Allow to request ROI edition from Flint
Feedback from BM18, and BCU people like @pguillou
People use to search in Flint GUI a button to edit the ROIs.
For now Flint is always used as a slave. Flint itself do not request anything to BLISS.
But we could make such button working. Cause since few BLISS version, there is a dedicated plot per Lima detector, which make the feature easy to implement.
