Event that emits with information about a changed Scripture Reference for a scroll group. Note it
also fires on a source-only change — a same-numbered reference set by a different-versification
project (the sourceProjectId changes while the verse numbers do not) — so consumers must not
assume it fires only when the verse numbers change; use the payload's sourceProjectId to tell a
frame change from a verse change.
