Add side-by-side 3D picture mode for a VR headset

[ugnich]

Could you kindly consider adding a side-by-side picture mode to be able to put the phone inside a VR headset like this one: https://www.aliexpress.com/item/1005006996500059.html
Thank you!

See this tool to understand what 3D mode settings the app should have: https://wwgc.firebaseapp.com/
I would recommend to do not rely on Google's QR codes and just let the user adjust all parameters manually + have a list of presets for the most popular headsets.

I got my headset already, will be happy to help with testing.
