Annotated lineages B.1.525, B.1.351, B.1.2, and B.1.1.318 on additional nodes to cover missing branches that caused missed assignments in Canadian sequences reported by Finlay Maguire.
Removed annotations for B.1.1.409 (indistinguishable to usher from B.1.1) and B.1.596 (indistinguishable to usher from B.1.2); will raise those issues in the pango-designation repo.
