The iCal parser returned master VEVENT components with their
original start dates instead of expanding recurrences. Events
from months ago appeared in today's feed.
parseICalEvents now accepts an optional timeRange. When set,
recurring events are expanded via ical.js iterator and only
occurrences overlapping the range are returned. Exception
overrides (RECURRENCE-ID) are applied during expansion.
