Crate correlation_flow

Calculates 2D image translation using image correlation

Could be used to:

• stitch image panoramas together (by calculating the point where two images overlap)
• measure optical flow (by measuring the 2D translation between image frames)

Constrained to operate in very low memory complexity on no_std rust for embedded systems.
