At some point the code changeover to use roaring iterators for unmarshal got dropped, but the old unmarshal code is way harder to make work for inspect, so this change is back. This exports some of the names from the things returned by Info, but also adds a roaring function to use the unmarshalling logic on arbitrary data, allowing us to get more insight into a file -- in particular, letting us distinguish between the bitmaps specified by the roaring data and the bitmaps resulting from applying the ops log.
