update the DRR example data package

[RobLBaker]

The current DDR example package is BICY - it's pretty dated and has some issues with it. It would be nice to use an updated example package with all the most up-to-date EML. It would be great if this data package had multiple data files.

It was suggested that the CAHA data package might be a good target data package, but that one only has one data file. Is there another one that we can agree to use for our group as well as for everyone else both inside and outside of NPS?
