Draft: Tupling MC samples for 2024 data validation with pi0/eta -> e+e-gamma decays

Tupling MC samples for 2024 data validation with pi0/eta -> e+e-gamma decays

Validating 2024 data with \pi^0 / \eta to e^+e^-\gamma decays and prepare for Dark Photon analysis with Run3 data.

Remaining ToDo list:

• Adding minBias for all nu's
• Dark Photon MC samples for \nu = 7.6
• Running HLT1, 2 and sprucing on MC samples (locally done already)
• Adding TISTOS-lines
• Retrieve 4-vector of pi+ from extra_output and save to tuples
• Improving DaVinci script
• Adding data later (need only to run DaVinci)

When ready:

• Remove the "Draft:" from the title:
• Assign the merge request to you working group's DPA/RTA liaison
