TODO

• Implement asave_video using OpenCV (as an optional dependency)
• Add docs for this
• Update the docs for saving files: usingframe instead ofsync_image_data
• Remove docs forsync_image_data and deprecate it? We should probably encourage manual syncing from now on
• Updateself.data when a frame is received
