Current Behaviour

Loading datasets from files (e.g. NEXUS files) creates an ImageStack with a default CIL AcquisitionGeometry.

Desired Behaviour

MantidImaging checks whether the file has an AcquisitionGeometry (i.e. it was written using the CIL NexusDataWriter class). If it exists, the loader reads the data (using the CILNexusReader class) and the ImageStack's AcquisitionGeometry is updated.
