feat: frameProcessorFps="auto" and automatic performance suggestions (throttle or increase FPS) (#393)

* Add `onFrameProcessorPerformanceSuggestionAvailable` and make `frameProcessorFps` support `auto`

* Implement performance suggestion and auto-adjusting

* Fix FPS setting, evaluate correctly

* Floor suggested FPS

* Remove `console.log` for frame drop warnings.

* Swift format

* Use `30` magic number

* only call if FPS is different

* Update CameraView.swift

* Implement Android 1/2

* Cleanup

* Update `frameProcessorFps` if available

* Optimize `FrameProcessorPerformanceDataCollector` initialization

* Cache call

* Set frameProcessorFps directly (Kotlin setter)

* Don't suggest if same value

* Call suggestion every second

* reset time on set

* Always store 15 last samples

* reset counter too

* Update FrameProcessorPerformanceDataCollector.swift

* Update CameraView+RecordVideo.swift

* Update CameraView.kt

* iOS: Redesign evaluation

* Update CameraView+RecordVideo.swift

* Android: Redesign evaluation

* Update CameraView.kt

* Update REA to latest alpha and install RNScreens

* Fix frameProcessorFps updating
