Time: NULL in uplink rx packet (GPS ENABLED)

We have changed our GPS module with “ u-blox 7 ” from then we were able to fetch the time and timeSinceGpsEpoch values.

The reason is that the HAL uses binary u-blox specific messages to retrieve the monotonic “GPS epoch” time. Technically you could use other GNSS modules, but you would need to extend the HAL library for getting the GPS epoch time.
