CAN_init shopuld be public

Then the application can call CAN_Ini if, for whatever reason, communication can not be established upon starting EPS32. In my case ESP32 is tarted before power to NMEA was provided.

  if ( updReinit.Update( 50000 ) ) {  // not to often
    unsigned int bus_status = MODULE_CAN->SR.B.BS;
    if ( bus_status == 1) {
       // bus off - reinit
      NMEA2000.CAN_init();
      TRACE( "Reinit bus" ); 
    }
  }

No. That should be handled on higher level on tNMEA2000, since also it has to be restarted. I have that on my version, but have not published it.
