      Load the data from a .ply file.
  
      Args:
          f:  A binary or text file-like object (with methods read, readline,
              tell and seek), a pathlib path or a string containing a file name.
              If the ply file is binary, a text stream is not supported.
              It is recommended to use a binary stream.
          path_manager: PathManager for loading if f is a str.
  
      Returns:
          header: A _PlyHeader object describing the metadata in the ply file.
          elements: A dictionary of element names to values. If an element is
                    regular, in the sense of having no lists or being one
                    uniformly-sized list, then the value will be a 2D numpy array.
                    If it has no lists but more than one type, it will be a list of arrays.
                    If not, it is a list of the relevant property values.
