Mixed sensor operation improvment:
A peak detector has been added to the adc measurement to avoid interferance while UART sensor are taking measurement while adc is active. The previous approach to shift adc into time windows where no UART were active had to be replaced because for the CO2 sensor is continously taking samples without providing a sync signal.
In addition the UART MUX switching behavior has been improved (potential rx data received from previous sensor is discarded during channel switch etc.)
