Additional actions on updatePinModes()

prepare a TX buffer with the necessary command sequence
initialize the corresponding RX buffer to zeroes to prevent false behavior
prepare a pointer array to direct data requests by getPin() to the correct place in the RX buffer
access the four AD5592R chips interleaved (especially for ADC configuration to ensure maximum time to track the signal)

More todos:

reduce the update() function to bare communication and let it use DMA (mind the CS pin management!)
add a start-/stopContinuousUpdate() function for automatic circular DMA communication
