Add ROI coordinates in table

[LauLauThom]

Problem with non-rectangular ROIs and if one mix and match ROI shapes
Ex: annotate a rectangle and then a circle -> not the same number of coordinates

Or a single column "ROI coordinates" with predefined formatting explained in the doc

Alternatives:

• activate the do Measure and select Bounding rectangle in the Analyze > setMeasurement menu
• annotations can be recovered from the ROI objects instead of the table (see README section). While the shapes coordinates can also be recovered using scripting (e.g. getXcoordinates for Polygons)
