nRF9160: MQTT Google Cloud ##################### This application gathers readings from a Bosch BME680 environmental sensor and publishes to a GCP Pub/Sub topic.
Sensor data is saved in an array of size set in prj.conf. When full, the data is aggregated, a TLS session is established, we authenticate to GC IoT Core and the data is published.
