Publish updates only on changes

[melyux]

There was already a check to only publish new status values when the status changed, but it had a bug: when comparing two nan values for outsideAirTemperature, the equality check would fail because nan == nan always fails in C++.

There was also already a check to only publish new setting values when the settings changed, but the line wasn't included in the otherwise empty if block (maybe by mistake).

Stage, sub mode, and auto sub mode statuses needed new checks, since it appears they were excluded from the settings by commenting out // this->heatpumpUpdate(receivedSettings) and not including them in the heatpumpSettings equality checks. Maybe this was a work in progress, or excluded later.

Closes #206

Thanks for your work
I will soon have a look

I think I remember why I ended up putting this->publishStateToHA(settings); outside the if brackets.

The connection to the module was systematically lost after a while.
Could you confirm if you're able to maintain a stable connection with this update?

For the second commit this->wantedSettings.power it'a a good find!!

I've had it running like this for about 24 hours and everything looks good. I tried turning on the unit with the remote control and the ESP received the right settings. Looking good! These changes don't affect the cycle communication with the unit as far as I can tell.

Not sure if this is related however I recompiled my install to see if it would fix my fan mode errors and now my esp32 crashes after startup. Is there a way I can install a prior version to see if it fixes the issue?

I had the same issue.
There is a typo on line 168 in hp_readings.cpp after the last commit. I have commented it in the commit and mentioned @echavet to hopefully bring it to his attention.

I see the problem. I'll make a new PR with the fix.

[melyux]

PR out with #213 should fix the typo
