Title: Update median_filter.cpp

Solving a linker error with Point type XYZI which is not precompiled for this filter. The solution that worked was to add #include . The correct way to make it more generic is to use :
PCL_INSTANTIATE(MedianFilter, PCL_XYZ_POINT_TYPES)
in the .cpp source file so that this instantiation is triggered in the corresponding .cpp file.
