feat: Create persistent CaptureSession to avoid any blackscreen issues or errors (#2494)
* feat: Create custom `CaptureSession` wrapper * Create `PersistentCameraCaptureSession` * Update VideoStabilizationMode.kt * Create RepeatingRequest.kt * Update CaptureSession.kt * Delete CaptureSession.kt * Update PersistentCameraCaptureSession.kt * Update PersistentCameraCaptureSession.kt * fix: Add `isRepeating` * Update CameraSession.kt * Make `SurfaceOutput` not `Closable` anymore * Update PersistentCameraCaptureSession.kt * Stub out the rest * Format * Set `isRunning` properly * Close previous outputs * onError callback * Format * Started/Stopped * Update CameraPage.tsx * Add `isValid` * Log `isActive` * Add `tryAbortCaptures` * Configure() * Try? * Add `didDestroyFromOutside` * Disable FP for testing * fix: Call `super.onAttachedToWindow` first * Hm * Update CameraSession.kt * Update PersistentCameraCaptureSession.kt * Try catch `didDestroyFromOutside` * Update PersistentCameraCaptureSession.kt * Session can only be active with a preview * Update PersistentCameraCaptureSession.kt * Throw `no-outputs` if needed * Update logs * fix: Check for CAMERA permission * fix: Close session when opening a new device * perf: Make everything `by lazy` in CameraDeviceDetails * Update CameraDeviceDetails.kt * Update PersistentCameraCaptureSession.kt * Update PersistentCameraCaptureSession.kt * Move * Update Podfile.lock * Implement `capture()` * Format * fix: Fix orientation not being applied * fix: Fix `isMirrored` * fix: Fix getting size * fix: Close `Surface` in `VideoPipeline` * Format * fix: Fix `VideoPipeline` not properly destroying itself * Use FP again * Update CameraConfiguration.kt * Rename * Clean up * Format * Update CameraConfiguration.kt * fix: Don't stop repeating request when capturing
