A well-temperament with six pure fifths

This does not stray nearly so far from 12-et, and Scala counts it as a
well-temperament. The little bit of 12-et in the middle of it isn't
something I put there; it falls out from the math when you take six
pure fifths centered on F#, and do a least-squares fit for the rest of it.
