Neighbor Stats in GUI are per Segment, not per Minute

[vuapo-eth]

To fix: Divide stats by segment interval:

const interval_ms = stats[1]["timestamp"] - stats[0]["timestamp"];
const interval_mins = interval_ms / 60000;
for(let i = 0; i < stats.length; i++) {
    stats[i]['new'] /= interval;
    stats[i]['all'] /= interval;
    // ...
}
