Message:
Changed file format to zFits; do not require all pixels to be at the correct voltage - this just takes unnecessarily long; stop trigger before switching voltage off or on to avoid a smartfact warning; allow to set the overvoltage; before moving ramp down the voltage to Uov=0; added single-pe run to shutdown; added task 'OVTEST'
