Data processing

Incoming telemetry data needs pre-processing before being displayed on the UI. For example: speed, max speed, apogee, deg/sec, time since last packet, gps lock (if an incoming packet has no gps block it means no lock)

@Chenguku just a heads up you might want to relay all the processed data periodically at 1hz instead of on every data change. I'm seeing a lot of slowdown of the UI already because of the sheer amount of telemetry we're sending.
