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.

+    Let us pray.
+    O Lord Jesus Christ, Who, when the love of many was waxing cold, didst
+    manifest once more the holy marks of thine own Suffering in the flesh
+    of thy most blessed servant Francis, to the end that our hearts might
+    kindle again with the fire of the love of thyself, be Thou entreated
+    for thy servant's sake, and grant to his and our prayers that we may
+    effectually carry thy Cross and bring forth fruits meet for
+    repentance.
+    Who livest and reignest with God the Father, in the unity of the Holy Spirit, God,
+    world without end.
+    ℟. Amen.
