Lucas CHOLLET cc1bd2d2d9 LibGfx/JPEG: Use a look-up table for cosine values 
This solution is a middle ground between re-computing `cos` every time
and a much more mathematically complicated approach (as we have in the
decoder).

While still being far from optimal it already gives us a 10x
improvement, not that bad :^)
