Lr1121 support

[FoxExe]

DIY parts:

• ESP32-S3 SuperMini board (4MB Flash + 2MB PSRAM, something like S3-Zero)
• Waveshare Core1121 module (LR1121-HF)
• WeAct Studios 2.9 e-paper module

Note: If your node hangs after sending a packet, check your DIO1 wire/trace. The LoRa module or ESP32 can generate heavy RF interference on it at high transmit power. This causes ghost interrupts, which completely breaks the radio's state logic and causes the device to freeze.
How to test: You can easily verify this by dropping the TX power to a minimum (around 10–14 dBm). If the freezes disappear, it’s definitely an EMI/noise issue on the DIO1 line.
