an engine capable of replacing sprites,
(still in progress).
update(0.2),
now capable of replacing numerous 2 by 2 grids,
thus making the replacement process 15X faster
than the previous version,
the spriteCore function can also be used individually
to replace just 1 grid (2 by 2),
I will soon make available my exec lua code,
also necessary to compress and import sprites for this
function and I will make a video teaching how to use it.
