audio/din: Update to 53.1

Changes since 53:

DIN Is Noise 53.1:
  ! fixed : runaway launch of drones when Drone Params > Defaults > Generations
            is > 1 (higher the value worse the outcome!) and Drones Per Minute = 0
            due to wrong initialisation of this drone parameter after DIN restart /
            reload

  Update ASAP to DIN53.1
