/**
 * Replace ids of affiliations associated with authors
 *
 * This does not change the ids of affiliations that are
 * not referenced anywhere or only referenced in funding,
 * as those ids do not come through to JATS.
 *
 * Also, it treats each frontmatter separately, so if one
 * affiliation appears in multiple articles/sub-articles,
 * it will be given a different id for each and be part
 * of the JATS frontmatter for each.
