Stage 1A - make OnboardIMU final

What's wrong?

private OnboardIMU imu = new OnboardIMU(MountOrientation.FLAT);

The imu should be private final, just for consistency's sake with the rest of 1A

Currently only the DifferentialDrive instance uses private final. Would it make more sense to make that only use private and have nothing using final?

Any thing that can be final should be. Final should be your default state when creating member variables
