Add SX1302 LoraWAN Gateway HAT for ChirpStack OS Gateway and Raspberry PI 4B

[dyane6]

I have a project to manage water metering sensors based on LoraWAN technology for my residence in France. I would like to create a LoraWAN Gateway 868 MHz based on ChirpStack OS Gateway, Raspberry PI 4B board and SX1302 LoRaWAN Gateway hat (www.waveshare.com). I have searched the issues of this repository and believe that this is not a duplicate. It could be a new hardware managed by the ChirpStack OS Gateway and easily integrated in the software https://www.waveshare.com/wiki/SX1302_LoRaWAN_Gateway_HAT

I don't know how to implement and introduce the new board by myself. I need help.
