This PR updates the antineutron CEX analysis task and the corresponding data model.

The following additions were implemented:

  • Counting of particles generated at the same secondary vertex, including:

    • charged particles
    • neutral particles
    • selected species (pi0, neutrons, gamma)
  • A new histogram for the angle between the line connecting the primary and secondary vertex and the z-axis.

  • A histogram to monitor the number of ITS inner barrel hits produced by the mother particle.

These additions are intended to provide more information about the topology of the interaction and the particles produced at the secondary vertex, which will be useful for further signal/background studies.
