A few changes to comply with upstream requirements for merge.
-Change input/output order from (out Labeled, in Image) -> (in Image, Out Labeled) and convert to Input/OutputArrays in the process. -Adopt OutputArray for statistics export so that the algorithm is "wrapper friendly" and not requiring a new struct in language bindings at the expense of using doubles for everything and slowing statistics computation down..
