Transmute element type into a new axis

[BTOdell]

I have an ArrayView<RGB8, Ix2> where RGB8 if from the rgb crate. This represents an RGB image with a width and height. I have my images in this format because it makes it easier to convert to a OpenCV Mat type for image processing. However, in some situations I need the data transmuted into a ArrayView<u8, Ix3> where the new axis is of length 3 for the red, green, blue color channels.

The array memory should already be in the correct format, so ideally I shouldn't have to iterate through every element and "expand" it manually into a third axis. Is there a way to do this?

This is a wanted feature. We have a proof of concept of this somewhere.
