IEDB data files need to be versioned somehow for provenance

[schristley]

This might be more about IEDB than tcrmatch and how the data files get released. I can see that the update scripts gives the old file a date but that's not sufficient for provenance. There really isn't a way to reproduce a tcrmatch run using the same data file if you don't happen to know and have an exact copy. I think it would be much better if the IEDB publishes new data releases with some sort of version number, as well as keep the old releases available.
