Support sorting probes by latency

[Alisson L.]

Sometimes I want to identify the probes with the best/worst latency to a specific host (to detect issues). It would be helpful to have the ability to sort probes based on their latency.

Thanks for this project, I'm currently hosting three probes.

Thanks for the feedback, I also want to add something like that. I think it will be done as part of this task jsdelivr/www.jsdelivr.com#578
