Specify target in href links

It would be useful to be able to specify the target in href links within vega plots. One example is plots within the Jupyter notebook, for which a normal <a href=""> changes the window and can lead to a loss of state.

It would be nice to let this percolate up to Vega-Lite as well 😄

I don’t have the time to make a full example right now but I think you can just pass a dictionary with {'target': '_blank'} to the Vega-Embed loader option property.

Added via updates to vega-view and vega-loader. Once the next Vega version is released, the following will set the default link target within the URL sanitization and loading system:

new vega.View(runtimeSpec, {
  loader: vega.loader({target: '_blank'})
});

Perhaps vega-embed should also be updated to expose target as a parameter?
