Feature Request: “Looking At” Support

[antgiant]

In your iOS app (Stellarium+) the sky position will update based on where the phone is aimed (looking). Could you please add support for that directly into the web version. It appears that Html5 supports all the needed sensor data. So, I'm hoping that means porting the feature is pretty straightforward. Just adding a button to click and trigger the permission request, and then behaving exactly like the App does from then on. Thank you.
