NineDOF API

[SheepSeb]

Pull Request Overview

This pull request adds:

• a 9-DOF API similar to the libtock-c version. The API provides a function that simulates a synchronous read of the accelerometer, magnetometer and gyroscope, also functions to initiate a reading, register/unregister a listener, check for driver existence, calculate the magnitude of the accelerometer
• an example app which samples the 9-DOF sensor every 700ms and prints the measured x,y,z for the accelerometer, magnetometer and gyroscope as well as the magnitude of the accelerometer
• a fake NineDoF driver, for testing
• unit tests for the fake driver and for the user space library

Testing Strategy

This PR was tested with the unit tests and by running the example app on a microbit v2 board
