Manually set camera id

[Tom60chat]

It will be nice to be able to manually set the camera ID, for multi-lens phones (ex: macro, ultra wide)

Sometings like :

cameraView.setCameraId("21")

I actually needed this functionality and that's why I was referring the discussions section and I found this, this is actually very important because most of the phones nowadays have multiple back cameras, and for that just FRONT & BACK options are not that much useful. I wanted to access ultrawide camera but right now there is no such option to use that.
