ETCS Braking Curves Output

- CoreETCSBrakingCurvesResponse
  - `conflicts` CoreETCSConflictCurves[], required — List of ETCS conflict braking curves associated to the train schedule's ETCS signals. For each non-route delimiter (F) signal, the associated spacing conflict curve is returned. For each route delimiter (Nf) signal, 2 sets of curves are returned, associated to the corresponding potential spacing or routing conflict.
