sortValues after rollup about d3-collection

[mbostock]

There is no guarantee that the rollup function returns an array, so it does not make sense to sort the return value of the rollup function.

However, it would be reasonable if nest.sortValues applied to the leaf values before the rollup function is called, even though in many cases (such as computing the sum of leaf values), it is not necessary to sort the input to the rollup function. Currently nest.sortValues is ignored when nest.rollup is used, but I think it makes sense to change it to sort the leaf entries before the rollup function is called.
