Chunk image jacobian #139

Closed ConnorStoneAstro closed 8 months ago

ConnorStoneAstro commented 8 months ago

Simple chunking scheme for large images. To prevent jacobian calculation from overloading the available memory, this will break up the image into sub-windows and compute the jacobian on them. Then it will stitch the images together to construct the full jacobian.
