xAOD SpacePoints EDM to GNN Dumper
This MR changes the DumpGNN4Itk dumper to use the xAOD EDM for clusters and space points instead of the InDet EDM. I've made a comparison between the outputs making sure that the cluster global positions, space point positions and indexing between clusters and space points is the same between the two versions. Using the xAOD EDM allows for having access to all the information that is used by ATLAS default track finding chain as well as be ready when ATLAS will switch to Acts-based track finding (which uses the xAOD EDM for clusters and space points directly) Here is a short comparison of the outputs before / after the change: https://cernbox.cern.ch/s/4mjnf5Tu0r6AtAS
I've added to the README an example on how to run the dumper as well as the flags to schedule the InDet:: to xAOD:: EDM conversion.
