* HAL: Fixed packet timestamp issue which was "jumping in time" in specific
conditions.
* HAL: Workaround hardware issue when reading 32-bits registers (timestamp, nb
bytes in RX buffer...)
* HAL: Fixed potential endless loop in sx1302_tx_abort() in SPI access fails.
* Packet Forwarder: Added global_conf.json.sx1250.US915 for US915 band
* test_hal_rx: added command line to specify RSSI offset to be applied
