Let's merge the SPI Transfers in the #RustLang Driver for LoRa SX1262 ... And make it work on Apache #NuttX OS

#RustLang Driver for LoRa SX1262 splits SPI Transfers into 1-byte and 2-byte chunks ... So this driver won't work on #NuttX OS unless we merge the SPI Transfers 🤔

But the #RustLang Driver for LoRa SX1262 doesn't run correctly on #NuttX OS 🤔
