Add September Matins readings for SanctiM-track saints

All 9 of September's SanctiM-track saints authored -- the first full
month in this pass with nothing left unsourced. Includes the
Dedication of St. Michael the Archangel, whose SanctiM file borrows
structure from his separate May 8 Apparition file but still resolves
its actual readings back to this day's own Tridentine content.

+        Hadrianus, jussu Maximiáni imperatóris apud Nicomedíam pérsequens Christiános, cum
+        sæpius eórum in fidei confessióne et tormentórum perpessióne constantiam demirátus
+        esset, veheménter ea re commótus ad Christum sese convértit. Quam ob rem cum aliis
+        viginti tribus Christiánis conjéctus est in carcerem; ubi eum visitans Natália uxor,
+        quæ et ipsa antea in Christum credíderat, ad martyrium incendit. Itaque, e custódia
+        edúctus, tamdiu flagellis cæsus est, donec intestína diffluerent. Postremo, fractis
+        crúribus, mánibus pedibúsque præcisis, una cum multis aliis martyrii certamen
+        feliciter absolvit.

+        Adrian was a man who was employed by the Emperor Maximian to persecute the Christians
+        of Nicomedia. The firmness with which they owned their faith and endured their torments
+        oftentimes excited his wonder, and at last so powerfully moved him that he himself
+        turned to Christ. For this he was thrown into prison along with three-and-twenty other
+        Christians. There he was visited by Natalia his wife, who also herself already had
+        believed in Christ, and by her urged on to lift up his testimony. When he was brought
+        out of prison he was lashed until his bowels fell out. His shins were then broken, and
+        his hands and feet cut off, whereafter, in company with many others, he brought to an
+        happy end the conflict of martyrdom.
