OpenMqttGateway BLE decoder

This is a really quick and REALLY DIRTY implementation of custom decoder for OpenMqttGateway, specifically for Xiaomi BLE devices with encrypted packets.

This was hacked together from a couple of different scripts found on github.

It expects OpenMqttGateway device to run my modified firmware.

Publishes decoded packets into home/mqttgateway_ble_decoder/{{MAC_WITHOUT_:}} topic.
