Add orientation ray

[Myzel394]

While switching from Google Maps to Qwant Maps I realized that probably the best feature missing is the ability to see where you're looking at. It would be really nice if you could see this on the map, like you can on Google Maps. For a reference, take a look at this image: https://imag.malavida.com/mvimgbig/download-fs/google-maps-11908-1.jpg (pay attention to the blue ray coming out from the blue circle where you are standing).

I can implement this feature if you would like to, I just need your ok

(I already opened this issue here, however, I am not sure which repo is correct)
