Since Accumulo does not normally create empty RFiles, its not a well tested thing. The RFile
unit test excercises creating an empty rfile and seeking it.  This ensures that an empty rfile
is readable.  I am wondering if its worthwhile to have an IT that covers the use case this
utility is intended for.   Could have an IT that offlines a table, replaces one of its files
with an empty rfile, onlines, and then scans.
