Reading multiple ROI's for aare
- read_frame, read_n etc throws for multiple ROIs
- new functions read_ROIs, read_n_ROIs
- read_roi_into (used for python bindings - to not copy)
all these functions use get_frame or get_frame_into where one passes the
roi_index
## Refactoring:
- each roi keeps track of its subfiles that one has to open e.g.
subfiles can be opened several times
- refactored class DetectorGeometry - keep track of the updated module
geometries in new class ROIGeometry.
- ModuleGeometry updates based on ROI
## ROIGeometry:
- stores number of modules overlapping with ROI and its indices
- size of ROI
Note: only tested size of the resulting frames not the actual values
