avoid deprecated lifecycles

Is this a bug report?

YES

I would suggest adding in Kotlin configuration Wiki section about how to select the custom resolution because it wasn't clear for me.
Something like that:

CameraConfiguration(
        ........
        pictureResolution = {
            filter { it.width in 1280..1920 }.minBy { it.area } // select custom resolution from available
        },
        ......
    )

Is your feature request related to a problem? Please describe.

Describe the solution you'd like
Ability to hide the bottom bar, or have it hide automatically when only one item is selected

Let me know if you need more info.
