For EMMAA gromets, on drill-down use statement hash to query metadata

Once we can visualize the EMMAA gromets in a more scalable way, we should be able to display statement metadata on the side panel using the statement hash provided in nodes. I think the workflow should be the following:

Click on a node from an EMMAA gromet and retrieve the metadata.
Identify the statement hash in the metadata object to query EMMAA.
Display that information in the side panel as we do it for graphs in the Graphs view.
