Pull request overview
This PR adds OpenMP-based multithreading support to the BoundaryEstimation class to enable parallel computation of boundary points. The implementation follows the same pattern used in other PCL features like NormalEstimationOMP.
Changes:
- Added
setNumberOfThreads()method to control thread count - Added OpenMP pragma directives to parallelize the main computation loops
- Added member variables
threads_andchunk_size_to manage parallel execution

getCoordinateSystemOnPlane(...) and isBoundaryPoint(...) should be marked as const, to make it clear that they do not change any class member. Looks good otherwise.
Calculcate normals only once.

The test case name "BoundaryEstimationOMP" suggests OpenMP-specific testing, but the implementation adds multithreading directly to the base BoundaryEstimation class rather than creating a separate BoundaryEstimationOMP class. This is inconsistent with how other OMP features are tested in PCL (e.g., NormalEstimationOMP in test_normal_estimation.cpp). Consider renaming this test to something like "BoundaryEstimationMultithreaded" to better reflect that it's testing the multithreading capability of the base class, not a separate OMP-specific class.
