psalter: transcribe the 16 psalms and 7 OT canticles Lauds needs

Ps 5, 35, 42, 50, 56, 62, 63, 64, 66, 75, 87, 89, 91, 117, 142, 148-150
weren't needed by any hour built so far. The 7 weekday OT canticles
(Isaiah, Ezechias, Anna, Moses x2, Habacuc, the Three Young Men) get
their own small store (src/hours/lauds-canticles.ts), separate from the
Psalter, since they use their own liturgical verse-numbering per
canticle rather than the Psalter's 1-150 numbering.
