Description
cv2.projectPoints takes very long because it always calculates and returns a jacobian matrix, which is huge for millions of points. It would be nice to just skip the calculation to only get the projected points

Research direction
Start at the cv2.projectPoints() API and inspect how its projected points and Jacobian are currently produced. Define an optional way to skip Jacobian calculation, then verify that projected points remain available without the large matrix while existing Jacobian behavior is preserved.
