Set new season + DPoW activation height to 340420

Hard fork heights must form a well-ordered set such that a < b, for every,
pair of heights listed in increasing order. There cannot be a fork height
which is less than a previous fork height, various boolean logic in deep
places will fail.

So we choose a height just after the z2z halving, approximately 9 hours
later at our new blocktime of 75 seconds.
