Fix Cantus reference

remarks
<a href="https://youtu.be/KoxvoCLupmc">Recorded by Ensemble Organum</a>, 'Graduel d'Aliénor de Bretagne: Plain-chant et polyphonies des XIIIe et XIVe siècles', conducted by Marcel Pérès (Arles: Harmonia Mundi, 1993), available at https://youtu.be/KoxvoCLupmc. For 'Kyrie eleison' and 'Christe eleison', the manuscript provides only an untexted reference line of music after the first verse. This edition follows Ensemble Organum's interpretation of this as a prompt for repetition of each verse's music, as an eighteenfold Kyrie. It may alternatively be a direction for untroped performance as a ninefold Kyrie.
