Update normal_estimation.cpp

Correct parameter order print in print_info
Clears inlier indices if save_inliers_ is true so that the same rejector instance
can be used in different runs. Side note: user code checking the returned inlier indices size
might be able to detect if consensus was found. Note that without this, when no consensus is found,
the filtered correspondences are equal to the input correspondences.
Added explicit overloads and instatiations for pcl::PointXYZ.
Supervoxel clustering can then be used with XYZ data.
