schemas/vegbien.sql: analytical_stem_view: cultivated: Use OR instead of _or() to combine cultivated_family_locations.country IS NOT NULL with the other values, because this field's false value should not be used in place of NULL if all the other values are NULL, as it would be with _or(). (cultivated_family_locations.country IS NOT NULL can indicate presence, but not absence, of cultivated status.)
