Dala.Camera (dala v0.0.1)

Native camera capture for photos and videos.

Requires :camera permission (and :microphone for video).

Opens the native OS camera UI. Results arrive as:

handle_info({:camera, :photo, %{path: path, width: w, height: h}}, socket)
handle_info({:camera, :video, %{path: path, duration: seconds}},   socket)
handle_info({:camera, :cancelled},                                   socket)

The path is a local temp file. Copy it elsewhere before the next capture.

iOS: UIImagePickerController. Android: TakePicture / CaptureVideo activity contracts.
