Changes in version 2.0.0                        

Breaking changes

  - All 20 Schaefer atlas objects (schaefer7_100 through schaefer7_1000
    and schaefer17_100 through schaefer17_1000) are now ggseg_atlas
    objects (from ggseg.formats) containing both 2D and 3D data. The
    separate _3d objects have been removed.

  - Use ggplot() + ggseg::geom_brain(atlas = schaefer7_400) for 2D plots
    and ggseg3d::ggseg3d(atlas = schaefer7_400) for 3D plots -- both
    from the same object.

  - ggseg.formats is now a hard dependency (in Depends).

  - Package URLs updated from LCBC-UiO to ggseg GitHub organisation.
