Upgrade OIDN to 1.1.0, the latest stable version that doesn't need
the ISPC compiler.
Documented the changes made during the removal of TBB and added a patch
file for them.
-Added LocalVector (needed it)
-Added stb_rect_pack (It's pretty cool, we could probably use it for other stuff too)
-Fixes and changes all around the place
-Added library for 128 bits fixed point (required for Delaunay3D)
