Beta 8v1.b8
- API: lgw_receive now return info on RX frequency and RF path for each packet (no need to keep track of RF/IF settings)
- Unified some portion of the code with the 470 MHz variant of the HAL (use SX1255 radios instead of SX1257)
- Improved AGC and ARB firmwares
- Adding -Wall -Wextra for compilation, fixing all the new warnings for cleaner code
- Fixed bugs in handling of FSK datarate
- test_loragw_hal now dumps the content of all Lora registers after configuration in reg_dump.log
