`resubscribe_subscriber`

Subscribes an unsubscribed subscriber again, with fresh consent: active, or pending on a list with double opt-in; the suppression its unsubscribe left is removed.

Call it: when the person asked to get the list’s mail again.
Needs: consent_source (where the consent came from), a live list, no other suppression of the list (remove the project’s or a manual one first, remove_suppression), and an admin key with project_id or a project key with scope write (its own project; the argument is ignored).
Returns: the subscriber after the call, the same as POST /api/v1/projects/{project_id}/subscribers/{subscriber_id}/resubscribe.
