Port Add height of cluster with the most points method #323 to master

[kosuke55]

I ported #323 to master. (ros2 -> ros1) height_thresh is a parameter to reduce the influence of point clouds that exist in high locations such as ceilings.

0: Smallest value among the average values ​​of each cluster (current method)

1: Largest value among the average values ​​of each cluster (current method which is implemeted only for ros1)

2: Mean value of the cluster with the most (new method)
