Add March Matins readings for SanctiM-track saints

All 6 of March's SanctiM-track saints authored. St. Benedict's own
patronal feast turns out to be the richest case in this pass so far:
its Nocturn 3 is genuinely Monastic-only content (a St. Peter Damian
sermon) absent from the Tridentine track entirely, unlike every other
saint done so far where the SanctiM file just reslices the same
Tridentine text. Also caught a case (St. Gregory the Great) where a
saint's SanctiM file carries content copied verbatim from an unrelated
feast rather than anything proper to the saint himself.

+        Licinio imperatore, et Agricolao præside, ad Sebasten Armeniæ urbem, quadraginta militum
+        fides in Jesum Christum, et fortitudo in cruciatibus perferendis enituit. Qui sæpius in
+        horribilem carcerem detrusi, vinculisque constricti, cum ora ipsorum lapidibus contusa
+        fuíssent, hiemis tempore frigidissimo nudi sub aperto aëre supra stagnum rigens pernoctare
+        jussi sunt, ut frigore congelati necarentur. Una autem erat omnium oratio: Quadraginta in
+        stadium ingressi sumus, quadraginta item Domine corona donemur, ne una quidem huic numero
+        desit. Est in honore hic numerus, quem tu quadraginta dierum jejunio decorasti, per quem
+        divina lex ingressa est in orbem terrarum. Elias quadraginta dierum jejunio Deum quærens,
+        ejus visionem consecutus est. Et hæc quidem illorum erat oratio.
+
+
+        Ceteris autem custodibus somno deditis, solus vigilabat janitor, qui et illos orantes, et
+        luce circumfusos, et quosdam e cælo descendentes Angelos tamquam a Rege missos, qui
+        coronas triginta novem militibus distribuerent intuens ita secum loquebatur: Quadraginta
+        hi sunt: quadragesimi corona ubi est? Quæ dum cogitaret, unus ex illo numero, cui animus ad
+        frigus ferendum defecerat in proximum tepefactum balneum desiliens, sanctos illos summo
+        dolore affecit. Verum Deus illorum preces irritas esse non est passus: nam rei eventum
+        admiratus janitor, mox custodibus e somno excitatis, detractisque sibi vestibus, ac se
+        Christianum esse clara voce professus, Martyribus se adjunxit. Cum vero præsidis satellites
+        janitorem quoque Christianum esse cognovissent bacillis comminuta omnium eorum crura
+        fregerunt.
+
+
+        In eo supplicio mortui sunt omnes, præter Melithonem natu minimum. Quem cum præsens mater
+        ejus, fractis cruribus, adhuc viventem vidisset, sic cohortata est: Fili, paulisper
+        sustine; ecce Christus ad januam stat adjuvans te. Cum vero reliquorum corpora plaustris
+        imponi cerneret, ut in rogum inférrentur, ac filium suum relinqui, quod speraret impia
+        turba puerum, si vixisset, ad idolorum cultum revocari posse; ipso in humeros sublato,
+        sancta mater vehicula Mártyrum corporibus onusta strenue prosequebatur: in cujus amplexu
+        Melithon spiritum Deo reddidit, ejusque corpus in eumdem illum ceterorum Mártyrum rogum
+        pia mater injecit: ut qui fide et virtute conjunctissimi fuerant, funeris étiam societate
+        copulati, una in cælum pervenirent. Combustis illis, eorum reliquiæ projectæ in
+        profluentem, cum mirabiliter in unum confluxissent locum, salvæ et integræ repertæ,
+        honorifico sepulchro conditæ sunt.

+        While Licinius was Emperor and Agricolaus President, forty soldiers at Sebaste, a city of
+        Armenia, gave a singular instance of faith in Jesus Christ, and bravery under suffering.
+        After being often remanded to an horrid prison-house, bound in fetters, and their mouths
+        bruised with stones, they were ordered out in the depth of winter, stripped naked, and put
+        upon a frozen pool, to die of cold during the night. The prayer of them all was the same: O
+        Lord, forty of us have begun to run in the race, grant that all forty may receive the
+        crown, let not one be wanting at the last. Behold, is it not an honourable number in thy
+        sight, Who didst bless the fast of forty days, and at the end thy Divine Law came forth to
+        the earth? When also Elias sought thee, Thou, O God, didst reveal thyself unto him when he
+        had fasted for forty days. Even so was their petition.
+
+
+        When the keepers were all asleep and the watchman only was awake, he heard them praying
+        and saw a light shining round about them, and Angels coming down from heaven, as the
+        messengers of the King, bearing nine-and-thirty crowns, and distributing them to the
+        soldiers. Then he said within himself: Are not forty here? Where is the crown of the
+        fortieth? And as he looked he saw one of them whose courage could not bear the cold, come
+        and leap into a warm bath that stood by; and the Saints were grievously afflicted.
+        Nevertheless God suffered not that their prayer should return unto them void; for the
+        watchman wondered, and called the keepers, and stripped himself of his clothes; and, when
+        with a loud voice he had confessed himself a Christian, he joined the Martyrs. When the
+        servants of the President knew that the watchman also was a Christian, they brake the legs
+        of them all with staves.
+
+
+        Under this torment died they all, saving Melithon, who was the youngest. Now, his mother
+        stood by, and when she saw that his legs were broken, but that he was yet alive, she cried,
+        and said: My son, have patience but a little longer. Behold how Christ standeth at the door
+        to help thee. When she saw the bodies of all the others put upon carts and taken away to
+        be burned, and that her son was left behind, because the multitude wickedly hoped that
+        being but a lad, if he lived, he might yet be drawn to commit idolatry, the holy mother
+        took him on her own shoulders and bravely followed behind the carts laden with the bodies
+        of the Martyrs. In her arms Melithon gave up his soul to God, and the mother who loved him
+        so well laid his body with her own hands upon the pile, with those of the other Martyrs,
+        that, as they had all been one in faith and strength, in death they might not be divided,
+        and might enter heaven together. After the burning, what remained of them was thrown into
+        a running stream, but the ashes were all washed together into one place, and being found
+        and rescued, they were laid in an honourable sepulchre.
