This PR extends the
MapFusiontransformation such that it also handles maps that are parallel.The functionality that had to be added is actually quite small, as the transformation already implemented all functions that were needed.
The only thing that was needed is some dispatch logic.

MapFusionwill by default not perform parallel map fusion, for this a flag has to be specified, theFullMapFusepass will do that.However, in auto optimize this is disabled for compatibility.
