DWA Fix wrong rotation direction

[goktug97]

After adding the rectangle obstacle calculation, I've tested the algorithm more to try different settings
and I've seen that sometimes robot hits obstacles, specifically during turns. I've realized, the yaw angle should be positive instead of negative while rotating the obstacles because of the dot order (a @ rot instead of rot @ a). After the change, the robot stops before hitting the obstacles.
