Camera state based control

[SuLG-ik]

Add PeekabooCameraState and PeekabooCamera that matches state flow.

Reason: old api with inner overlay has no abilities for advanced usage of camera. For example, if i need to handle progress state outside of PeekabooCamera, i add external boolean state of is in progress and add disposable effect inside progressIndicator to change this state and handle it outside PeekabooCamera, for example, to change captureIcon.

var isCapturing by remember { mutableStateOf(false) }
PeekabooCamera(
    modifier = Modifier.fillMaxSize().padding(it),
    cameraMode = CameraMode.Back,
    progressIndicator = {
        DisposableEffect(Unit) {
            isCapturing = true
            onDispose { isCapturing = false }
        }
    },
   / * ... */
)

Benefits: camera overlay become more flexible and in future PeekabooCameraState will be able to have advanced features of camera control.

Note: camera underhood is not changes, only provide actions to new state api. Old api saved for compatibility, but underhood rebased on state
