How to use the pyansys._binary_reader.affline_transform function in pyansys

"""In-place 3d transformation of a points array given a 4x4
    transformation matrix.

    Parameters
    ----------
    points : np.ndarray or vtk.vtkTransform
        Points to transform.

    transform : np.ndarray or vtk.vtkTransform
        4x4 transformation matrix.
