Throw an error on non-zero k4, k5 or k6

[Yubel426]

Hi @jb-ye @devernay, why is there a problem when k4 is not equal to 0? #3355 #3381 When reading the camera distortion coefficients such as this, k4 is correctly assigned as the fourth-order radial distortion coefficient rather than the fourth coefficient. The current approach makes data with non-zero k4 coefficient like fisheye unusable.
