Choose multiple servers and render graphs for each

[dc7707]

Is your feature request related to a problem? Please describe.
It's not so much a problem, but it could be useful to see results from multiple servers to rule out one server being slow at the moment of testing.

Describe the solution you'd like
An option to test multiple servers in the settings.
A box to select the servers like the existing one for using one at a time.
When enabled and selected a speedtest is ran against every selected server (with an apropriate delay so they don't get in each other's way), and graphs are rendered for each.
When looking at the graphs one could get a good idea of their performance by averaging them. (This could also be calculated and displayed in some way.)

Additional context
I know this isn't a big deal for most people, but I think it would be cool. Thank you for taking the time to read this request, and thank you for this wonderful tool!

Agree. This would be very useful. By default speedtest uses a server in the provider's network which is not a good measure of Internet speed but actually how congested is the provider's network. If I chose a server from another country I could see Internet speed, but I would like to have both.
