/// Using the quantum teleportation algorithm to mix 2 greyscale images. This is A LOT FASTER than the other Teleport method.
/// It splits the image into smaller images, which can be progressed way faster and then puts them back together.
/// Can sometimes have some slight errors in images with big blocks of black pixels.
/// Else it uses the same method of using teleportation to swap placed between the 2 images.
/// Teleportation progress of 0 means no teleportation, Teleportation progress of 1 means the teleportation finished.
/// And Teleportation progress of 0.5 means it is right in the middle.
