Add optional returnWaterTemperature sensor

[Jalle19]

Mutually exclusive with exhaustAirTemperatureBeforeHeatRecovery.

@ajulk7 if you know your way around git, please try this branch and let me know if the values look correct!

Nice, I’ll test it later today.

Seems to work, returnWaterTemperature reading is shown and value is correct. 👍
