Some branch lengths systematically too long #79

In this example comparing the sc2ts tree with nextstrain, the root of the clade seems to be quite a bit too recent. I think this is because we're not doing the branch lengths above reversion pushes and mutation coalesces (hereish) in a sensible way. We can verify this by looking at the type of node that the clade root is.
