Fixed a thing

just a quick fix to make DOVL cache triggers in the same way as OVL.

I also changed how timeseries are reported to make sure that the reporter (and filename) respects the actual amount of data included. This won't matter in most cases, but when ignore_segdb=False we sometimes get series that do not span the entire range covered in that stride/segment. Now, idq.batch.report_timeseries iterates over the actual segments produced and creates a separate file for each. This will likely prevent confusion+consternation later on.
