This generalises the test I added in #146 to make it easy to test any widget that takes a single layer as input. Although we only have two widgets at the moment, any new widgets just need to be added to
@pytest.mark.parametrize("widget_cls", [HistogramWidget, SliceWidget])
in the future and they'll be automatically tested.More work towards #7.
