do not daisy chain output attenuators #19

AFAICT we have enough IO to put each ADC gain and each DAC attenuator on a separate bus. This is vastly preferable since it means that we don't have issues where programming one attenuator reprograms all others (which is a PITA in the current Urukul implementation)
