HADES / HADCON: triple redundancy 1-wire ADC readout

• in an noisy environment, the 1-wire ADC readout (via OwAdc1) used at several places suffers from spikes
  • w/ a typical scan rate of 0.1-1 Hz a falls signal may be persistent for almost 10 seconds, provoking false interlock signals
  • e.g. differential pressure measurement MDC
  • absolute pressure measurement
• implement to HADCON 1-wire control command OWAD a feature, to perform a triple read of a channel, and remove a possible spike
