Adds new INI config option
rearchive_reports_in_past_exclude_segments to disallow archiving segments when rearchiving in past. Should be fine for things like plugin activations and entity creation, but I can see one issue w/ updating an entity. If there is already segment data for the old entity, then that will be displayed as if it is new. Perhaps this should also be paired w/ a new feature that doesn't use archive data if it is older than the entity last update time? This would require being able to set the last update time in, eg, a Report or ViewDataTable class and checking this against the
ts_archived. I imagine there would be support requests if we just show the old data.
Also includes a small bug fix (processed $idSites value not being used in applyScheduledRearchiving).
