A simple implementation of Threadline.ExportQueue using Task.Supervisor.
It spawns a background process using Task.Supervisor.start_child/3. By default,
it expects a supervisor named Threadline.Export.TaskSupervisor to be running
in the application tree, but you can override this by passing the :supervisor
option in opts.
