Surprising (extreme) values flagged during the last update()

Returns a tidy data.frame with one row per flagged surprise – currently the reporting delays that arrived later than the model expects (surprise = "delay", direction = "long") – together with their tail probability and the level used. Returns NULL when nothing was flagged (or surprise was not computed).
