New Features

support config option REQ_MESG_DEL_ACK: boolean configuration that defines whether to request for Message Delivery Acknowledgement. When transmitting messages over MQTT, this controls the QoS. REQ_MESG_DEL_ACK=True results to QoS=1. REQ_MESG_DEL_ACK=False results to QoS=0
Re-support old insigh.io boards with scale sensors
Support ESP32-wroom
Support Remote Tare request
Initial support of remote partial configuration request
