Expanded Sensor map structure: In the previous version the number of possible sensors were set to 5 based on the assumption that ADC slots are shared with digital O2 sensors. As result three of five slots would have been limited to O2 measurement usecase, leaving just two slots left for other sensors (e.g. CO2). In order to have as much flexibility (and less risk for data structure changes) the number of sensors has been set to 7 (3 ADC + 4 UART MUX)
