Detailed Description

LR1121 radio driver implementation for IO-Homecontrol.

See radio_lr1121.h for the architectural context: this driver is a re-plumbed RadioSX1262 over a different SPI command set. Everything about the software UART PHY (TX bit-encoding, RX probe/CRC recovery) is identical to the SX1262 and lives in radio_soft_phy.{h,cpp}; the IRQ-driven RX/TX orchestration both drivers share is in SoftPhyDriverBase (radio_soft_phy_driver_base.{h,cpp}). This file only has to reproduce the LR1121-specific transport (16-bit opcodes, two-transaction command/response, 32-bit IRQ word) and the chip's own GFSK/RF-switch/TCXO/PA configuration.
