STM: Separate Status and Counter Messages

[MeierTobias]

At the moment each message contains both the device status and the timeseries of counts. If this is separated we could lower the transmission rate (improve the battery lifetime)

Status Message:
Same as before but aggregated over a day and then sent only once per day.

Count Message:
Here we could aggregate the count even further for example in to 10min bins. (Or even more). I think we don't need the current 1 minute accuracy.

I would suggest to only deploy this to the STM devices because we have a somewhat high message loss on the Arduino devices (due to the down-link ack bug in the mkrwan library)
