solves issue #890

  • introduces resolution factor for pixel measurement (experimentally evaluated)
  • therefore removes "magic" factor in the aperture angle
  • does not assume small angle approximation any longer (as 21 degree is not that small)
  • fixes wrong Npix number
  • removes omega_factor, which had no mathematical reason
  • updates dt in every measurement, not only in those with detected movement (as we work with velocity/rates in the update, so we assume them over all of dt and don't want the time without movement to have an effect)
