rite(ef): season and rank vocabulary per RG 71-77 and RG 8

Eight seasons in canonical liturgical-year order, each carrying its RG
citation, and the four classes. season_slug_word is deliberately distinct from
season_to_string: slugs are lectionary keys adopted verbatim from lectio,
which calls Paschaltide 'easter' and Christmastide 'christmas'.
