Add radius search to KDTreePCLAdaptor object
- For now all searches in a kdtree are performed with knn number of neighbors (KdTreePCLAdaptor object).
- This MR aims at adding a function to do the search with a radius parameter.
- It does not change the actual SLAM process in any way and does not add any option to the user.
- It is needed when using KdTreePCLAdaptor.h outside slam process.
The radius cannot be used because of perf issues.
