Netatmo: last_updated is not updated if the value doesn't change

[cnotin]

The problem

Thanks for your work on this integration!

I noticed that the last_updated of a temperature sensor is not updated if the temperature value doesn't change. My understanding is that it would be updated, so we can know that a recent data was fetched, even though it didn't change.
The last_changed isn't updated either but this seems normal for this one.

I assume that the data was correctly retrieved though because the same Netatmo sensor has other attributes, like humidity, whose value changed and for which the last_updated was updated.

Is this expected?
