Mi Flora consistent MQTT protocol

[torwag]

I just noticed that the RSSI value is send by e.g. :

home/BTtoMQTT/445F3666113E -085

whereas all other data is send by adding a subtopic e.g.:

home/BTtoMQTT/445F3666113E/temp 20.0
home/BTtoMQTT/445F3666113E/moi 10
home/BTtoMQTT/445F3666113E/lux 500

This makes it unnecessary difficult to parse the MQTT topic, as it is not consistent.
If the RSSI value will be send in the same way e.g.:

home/BTtoMQTT/445F3666113E/rssi -085

parsing would be easier and the meaning of the payload would be more clear to beginners.

@torwag could you test the changes from master and say me if ok for you?

Looks good to me, flashed a second board with the new code and it seems to work as desired.
I created a fork and did the changes myself, however, did not had time to test them and create a PR.
BTW. I couldn't find how the trc command is used. Seems to be a debug command, but couldn't find any infos about it.

For releasing, it might be a good idea to publish both statements (old way and new way) for the next release and announce in the changelog, that the old way will be deprecated with the next release. This gives people time to adust their code to the new system.

Thanks for the changes.

Yes trc is a debug command that can be deactivated in user config. It enbles to see the traces on the serial monitor.
