HeronSquawk: reconstructing RYLR999 LoRa framing for a mesh network

HeronSquawk reconstructs the RYLR999 LoRa module's on-air framing from SDR captures so it can exchange packets with Heltec V3.1 SX1262 nodes. The resulting mesh system combines a Python desktop base station, MicroPython node firmware and an Android BLE client, with encrypted messages routed across nodes.
