/// Processes ARKits' ARFrame->capturedImage CVPixelBuffer according to the documentation into an sRGB image.

/// ARKit captures pixel buffers in a full-range planar YCbCr format (also known as YUV) format according to the ITU R. 601-4 standard.
/// (You can verify this by checking the kCVImageBufferYCbCrMatrixKey pixel buffer attachment.)
/// Unlike some uses of that standard, ARKit captures full-range color space values, not video-range values.
