Review 10-12 bit conversion for all inputs

[DeeEmm]

Review all sensor inputs:

• Convert from 5v to 3.3v reference
• Convert from 10 bit to 12 bit resolution

[DeeEmm]

Have already updated MAF sensor and board voltage reference (#79). Need to roll out for remaining inputs prior to unit tests (#76)

Example conversion (from MAF sensor)

int mafFlowRaw = analogRead(MAF_PIN);
double mafMillivolts = (mafFlowRaw * (_hardware.getSupplyMillivolts() / 4095.0)) * 1000;
return mafMillivolts;

NOTE:

_hardware.getSupplyMillivolts()

References 3.3 volt supply and integrates supply fluctuations into sensor calculations.

4095 bit resolution = 12 bits

Remaining references to 10 bit / 5v replaced
