generate_segments docstring

[ajjackson]

The docstring for effmass.extrema.generate_segments seems to be outdated:

Generates a list of Segment objects.

Args:
    extrema_array (array(int)): A 2-dimensional array of size (number of extrema, 2). Each row corresponds to an extrema and contains [:attr:`~effmass.inputs.Data.bands` index, :attr:`~effmass.inputs.Data.kpoints` index]. See :func:`find_extrema_indices`.
    Settings (Settings): instance of the :class:`Settings` class.
    Data (Data): instance of the :class:`Data` class.
    truncate_dir_change (bool): If True, truncates eigenstates when there is a change in direction. If False, there is no truncation. Defaults to True.

Returns:
    list(Segments): A list of :class:`Segment` objects.

There is no extrema_array argument?

Thanks @ajjackson I have updated the docstring here.
