Please add the orientation sensor to the documentation

[arthedza]

We have already released the functionality of the orientation sensor (#349) but its description absolutely absent in the docs.

[DanielMSchmidt]

I'm happy to review a PR about this :)

 const sensor = Sensors['orientation'];
       const subscription = sensor.subscribe((values) => {
         console.log(values);
       });

@DanielMSchmidt the docs have already been updated in abe80e7 on PR #349

deploying the latest docs/API.md should add it to the documentation
