add BuildingBlockParam<bool> force_sim_mode{"force_sim_mode", false}; in U3VCameraN if set to true, U3VCameraN begin simulation U3VCameraN can also fallback to simulation modeif there is no device found on the host

 unsigned int n_devices = arv_get_n_devices ();
  if (n_devices == 0){
      log::warn("Fallback to simulation mode: Could not find camera");
      sim_mode_ = true;
  }
