ACR Object orientation - bugfix

[sophie22]

Account for fluctuation in ImagePositionPatient values in all directions - assume that "true" orientation is where values across the image set are changing. When the orientation cannot be determined from DICOM metadata values, error out and do not attempt to assume orientation. - In the future, provide an optional CLI argument to override orientation and provide the axis to be used for orientation.
