NEQR_example_4_pixel_8bpp.py

The example from the paper to load 4 pixels of 8 bits per pixel grayscale into NEQR representation (with Espresso boolean simplification of the circuit):

NEQR_example_4_pixel_8bpp_with_image_inversion.py

The same image as NEQR_example_4_pixel_8bpp.py is loaded, then inverted via quantum NOT gates
