Plot legend must be unique identifier of scan data

[padraic-shafer]

The 'legend' used by the ScanWindow must be a unique key for each plotted curve. It is expected (although perhaps not enforced?) that the legend should include the source name and scan key. ScanWindow will make a copy of the DataObject it receives and append the y channel name (i.e., the data_key for a BlueskyRun).
