Maqueen Plus V2.1 has some changes from V2.0

The ADC addresses are reversed.

    const ADC0_REGISTER = 0X1E;
    const ADC1_REGISTER = 0X20;
    const ADC2_REGISTER = 0X22;
    const ADC3_REGISTER = 0X24;
    const ADC4_REGISTER = 0X26;

So instead of R2 having an address of 0x1E it will be at 0x26 instead.
Do we need a new repository? Can we look at the version when we init and change them accordingly?
