   When given multi-file data with multiple coordinates, the previous behavior was to include every coordinate as a dimension. This is logical for scans such as 4D position-dependent scans, but unnecessary for data like hv and angle dependent scans. Now, the loader will concatenate only along one axis if all motor coordinates are strictly monotonic.
