Split out targetFlowTemp and targetRoomTemp in MyHeatPump app.

[dfeist]

Target Room Temperature and Target Flow Temperature are two quite different things. Using a single field for these has the following issues:

• It is unclear who is using it for target room vs. flow temp (therefore reducing value of the field for anyone other than owner)
• Unable to show target room and target flow temperatures.

Being able to see both target room and target flow temperature in the app and https://heatpumpmonitor.org/ is invaluable for understanding and monitoring the control strategy that is in use including i) day/set-back temperature ii) weather compensation in operation etc.

I propose that the app has both of these value seperatly. While not everyone will be able to provide these values they are generic parameters that apply to all installs.
