Proposed new feature or change

Suppose that I have a list of indexes
indexes = o3d.utility.IntVector( [10,20,30] )
and I want to select these indexes from the FPFH descriptors:
FPFH = o3d.pipelines.registration.compute_fpfh_feature(cloud, kd_tree_descriptor)
I could do
FPFH.select_by_index(indexes) but:

'open3d.cpu.pybind.pipelines.registration.Feature' object has no attribute 'select_by_index'

I can convert the FPFH features to numpy arrays:
FPFH = np.asarray(FPFH.data)
FPFH = FPFH.transpose()

and then select only the rows that I want
FPFH = FPFH[indexes]

But now, there is no way to convert the FPFH numpy array back to a feature object.
