Data view for Histogram1d

It would be great have a data view for `Histogram1d` objects in order to do something like this:
```
Histogram1d histogram = ij.op().image().histogram(img);
ij.ui().show(histogram);
```
Currently this crashes with `java.lang.ArrayIndexOutOfBoundsException: 1` at [this line](https://github.com/imagej/imagej-common/blob/master/src/main/java/net/imagej/display/DefaultDatasetView.java#L340) because the `DefaultDatasetView` cannot handle 1D.

Start at the referenced line in src/main/java/net/imagej/display/DefaultDatasetView.java and trace how dimensionality is handled when displaying a Histogram1d. Reproduce the shown ij.ui().show(histogram) case and determine the relevant display path. Done means Histogram1d objects can be shown without the ArrayIndexOutOfBoundsException.
