Calls the given callback function for each occurrence of the event that intersects the range between the given start and
end times (the end time is not included).
Note that the occurrences may start before the given start time.
If the callback routine returns FALSE the occurrence generation stops.
The start and end times are required valid times, start before end time.
The get_tz_callback is used to resolve references to timezones. It is passed a TZID and should return the ICalTimezone *
corresponding to that TZID. We need to do this as we access timezones in different ways on the client & server.
The default_timezone argument is used for DTSTART or DTEND properties that are DATE values or do not have a TZID (i.e. floating times).
