Merge pull request #755 in VECTO/vecto-sim from ~EMQUARIMA/vecto-sim:bugfix/VECTO-967-engine-only-mode-engine-torque-reported-in-.vmod-does-not-match-the-provided-cycle to develop

* commit '0ca63d2d':
  fix: time offset in .vmod file - first entry in cycle is assumed to be steady state, first simulation step uses 2nd entry in cycel
  fix: don't re-compute engine torque from average enine power with average engine speed
