Port BeamSpot4D to Gauss-on-Gaussino for U2 studies
While BeamSpot4D is merged into Sim10 since Gauss v55r2, it is not currently in Gauss-on-Gaussino. Following discussion with Velo/Calo (https://indico.cern.ch/event/1180161/) ask to port to Gauss-on-Gaussino.
To be understood:
- Is this LHCb Specific? If so, target Gauss/Futurev4, otherwise, target Gaussino.
- Multithread compatibility to be tested
- Integration Tests
- Options to be added
