Description

The Teragen algorithm is no longer up to date with the sortbenchmark.org gensort tool used for the official sort benchmark. The new algorithm is supposed to generate data that isn't very compressible.

Also the new version of gensort can generate skewed data so we should add that option to teragen also.
