Pitot (aarch64)

Continuation of Nicd's harbour-pitot for aarch64. Source: https://github.com/sharks-dev/harbour-pitot. Original application description as follows:

Pitot is a GPS/GLONASS speedometer for your SailfishOS device. It will show you the speed of your device in big, friendly letters. It supports all orientations and has a bunch of different units to display the speed in.

Note that due to the inaccuracy of the builtin GPS receiver on the Jolla, the following problems may occur:

• Speed is measured in increments of about 0.25 meters per second, so between 0.25 and 0.5 there are no other values.
• Speed values may fluctuate rapidly depending on the quality of the GPS fix.
• Sometimes the device's GPS receiver thinks it is moving at a constant rate, even though you have stopped.
• Getting a GPS fix may take a long time.
• There is no reliable way for the application to tell if location services are turned on, so if they are turned off while the application is running, the speed will freeze until they are turned back on.

These are issues with the device's GPS receiver and/or QtPositioning implementation and cannot be fixed.
