v5.0.0

HAL: Changed GPS module to get native GPS time (monotonic, no leap second). WARNING: The native GPS time is not given in standard NMEA messages, so we get it from a proprietary message of the GPS module used on gateway reference design, u-blox 7. If you are not using the same GPS module, you may have to update the lgw_parse_ubx() function.
HAL: Added lgw_cnt2gps() and lgw_gps2cnt() functions for SX1301<->GPS time conversion.
HAL: Changed serial port configuration for GPS to properly handle binary messages (UBX).
HAL: Added a lgw_gps_disable() function to restore serial configuration as it was before HAL initialization.
HAL: Fixed packet time on air calculation using the actual packet preamble size.
HAL: Adjusted TX_START_DELAY based on the board reference design to ensure that a packet is sent exactly at 1500µs after the TX trigger (TIMESTAMP or PPS), with a tolerance of +/- 1µs. This is mandatory to comply with LoRaWAN specification for Class-B beaconing precise timing. WARNING: This release provides tx start delay values to be used for Semtech reference designs AP1 and AP2. The HAL automatically detects the board version by detecting a FPGA or not. If you are using a different reference design or a different FPGA binary version than the one provided with this release, the value to be used for TX start delay may be different.
