Plot ROIs on the flatmap

ROIs are defined as sub-layers of the roi layer in <filestore>/<subject>/overlays.svg

By default, ROIs and ROI labels are displayed when a flatmap is plotted using quickflat.make_figure.

with_labels=False turns off the ROI labels. with_rois=False turns off the ROI display.
