Make Horizontal Joins Easier and Faster

[CraigMiloRogers]

The kgtk join command performs a logical join of edge records or node records through concatenation of records. Sometimes the desired use case is to compact the records, producing a single output record with the additional column data from both sources.

This use case can be supported through the pipe kgtk join / compact.

If we add --compact option to kgtk join, we can reduce the complexity of the user's command line and gain a substantial performance improvement by avoiding Python I/O.
