Don't remove all parents that have a worse rank than an incoming DIO: we may inadvertently remove our preferred parent. Instead, remove parents with a rank that is worse than our preferred parent. If we are lucky, this will give us enough space for the new parent.

Rewrote the parent selection to favour parents with a low ETX and a good rank. The old parent selection would always favour parents with a lower rank, regardless of their ETX, which in some cases lead to suboptimal parent selections. Also, the old code was buggy in that it would always pick the worst parent (the one with the highest ETX).
