View ice labels on a dump. The engine writes LAMMPS text. The
viewer for this release is solvis (PyVista) through
`pydseams <https://d-seams.github.io/PydSEAMSlib/>`_, not OVITO.

.. code:: bash

    pip install 'pydseams[solvis]'

.. code:: python

    import pydseams as ds

    frame = ds.read("input/traj/exampleTraj.lammpstrj")
    frame.chill_plus()
    frame.cages()
    system = frame.to_solvis()

``system`` is a ``solvis.System`` on the same ``Atoms`` ``to_ase``
returns, including ``ice_type`` / ``hc`` / ``ddc`` arrays after those
calls. Interactive plots follow the
`solvis examples <https://github.com/amritagos/solvis>`_. The full
howto is `pydseams solvis <https://d-seams.github.io/PydSEAMSlib/>`_.
