Dragino LT-22222 LoRaWan Controller

Hi,

following indications from the AWS Workshop, I was hoping the following LoRaWAn controller could be added as end devices for LoraWan:
Dragino LT-22222

Thanks a lot

No file or test is identified in the request. Start by locating existing LoRaWAN end-device support and binary-decoder entry points in the repository, then compare how another device is represented; done means the Dragino LT-22222 is supported consistently with those existing devices and its behavior is covered by the relevant tests.
