Target Interaction

We want to be able to use different generators for the target interaction. This should be possible in DD4hep. Another project did this to use ML in the ECAL (https://github.com/key4hep/DDML)

It is probably better to simulate distributions beforehand and then let dd4hep pick from these distributions in the target but needs to be evaluated

We want to use

• FLUKA for hadronic backgrounds
• some dark photon specific generator (from Martin?)
• Something for QED
