Add reco info
Add reconstructed variables from proto-tracking to root output. Convert and save them as awkward arrays in a h5 file.
The variable are the track position and x,y slopes, the track's point of closest approach w.r.t. beamline and it's covariance in x,y which is currently only a single number:
- recon_x,
- recon_y,
- recon_z,
- recon_tx,
- recon_ty,
- recon_pocax,
- recon_pocay,
- recon_pocaz,
- recon_sigmapocaxy,
