Benchmark to verify simulation beamline optics

The benchmark aims to verify that the optics used in the dd4hep epic simulation match those expected by the eic machine.

Proposed components of the finalized benchmark:

- [x] Plots showing the position, momentum and correlations for beam electrons passing through the beamline magnets. https://github.com/eic/detector_benchmarks/pull/154
- [ ] Link directly to machine distributions.
- [ ] Generate events using the afterburner.
- [x] Energy-theta acceptance at each virtual detector.
#167
- [ ] Create check and feedback comment to epic PRs which don't pass or significantly change acceptance
- [ ] Labelled beamline geometry visualization output.
- [ ] Extend to include far-forward protons
- [ ] Create report pdf, tidying up all plots.
- [x] Train onnx neural network to reconstruct initial particle and produce resolutions.
#171
- [x] Create pipeline to automatically update the onnx network used in the reconstruction.
