[Collisions] Datasets to use for older years

You should be able to find CLEAN data for every year, if you prefer that.
FYI the clean data differs from the raw data in the following ways:

   - files begin and end on consistent time boundaries.
   - pcap files have the same datalink type.
   - Any non-root traffic is removed.

If you prefer to work with the RAW data make sure you pay attention to the
server's IP address during the analysis.  In some cases non-root-trafic
has been known to "leak" into the DITL data.  Also there were times where
J-root data was uploaded as A-root, and perhaps vice-versa.
