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
