Add September sanctoral content: 10 saints/feasts

Continues the full-year sanctoral import: St. Stephen of Hungary, St.
Pius X, St. Lawrence Justinian, Ss. Protus and Hyacinth, the Holy Name
of Mary, the Seven Sorrows of the BVM (Duplex II Classis, own full
proper content except Nocturn 2, a real cross-reference to Passion
Friday's own temporal content), the Impression of the Stigmata of St.
Francis, St. Joseph of Cupertino, Our Lady of Ransom, and St.
Wenceslaus.

Ss. Protus and Hyacinth (Sep 11) were previously excluded under a
stale "real secondary saint blocked by the Nativity's own octave, same
as St. Clare in August" note -- wrong, same class of error already
corrected for St. Tiburtius/Susanna in August: the octave-window
exclusion was never a real rule. Sep 15 (day 8 of the Nativity's own
octave) is now also the Seven Sorrows' own fixed day (Duplex II
Classis), which wins outright with the octave still commemorated
alongside her -- updated september-sanctoral.test.ts's own "excluded
secondary saints" case accordingly, splitting it into the still-valid
Sep 9 (Gorgonius) half and a new Sep 15 case reflecting the real
winner.

+    O God, at Whose suffering the prophecy of Simeon was fulfilled, and a
+    sword of sorrow pierced through the gentle soul of the glorious Virgin
+    and Mother Mary, mercifully grant that we who speak worshipfully of
+    her woes, may obtain the saving purchase of thy suffering.
+    Who livest and reignest with God the Father, in the unity of the Holy Spirit, God,
+    world without end.
