Parse LoRa payload sent by the Ranos dB

The Ranos dB is capable of sending a variety of values (dB(a), dB(c), Leq(a), Leq(c), GPS coordinates, battery voltage and more). Which values are sent, the send interval, the number of measurements per LoRa message, the LoRa spreading factor and more can be configured using the Android App. This means that de LoRa payload differs based on the configuration of the sensor. Besides this, the payload is compressed due to the LoRa payload length constraints.
