Update README.md (#6)

More accurate statement in the readme, the system does not need to follow a unicycle motion model, just the pose correction needs to do that, which applies to much more robotics platforms.

-Kinematic ICP can enhance existing odometry using a 3D LiDAR. However, there are specific requirements regarding motion and transformations due to the assumption that the robot operates on a unicycle kinematic model. Below are the key requirements:
+Kinematic ICP can enhance existing odometry using a 3D LiDAR. However, there are specific requirements regarding motion and transformations since we use a kinematic motion model for the pose correction. Below are the key requirements:
 
 1. **Planar Movement**: The robot is expected to move primarily on a planar surface.
