Send found results to speedtest.net API and get image

Hello

In you todo i can see "Send found results to speedtest.net API (needs some hash?) and get the link to the generated image."
I don't know if you know but there is already an implementation (in python), https://github.com/sivel/speedtest-cli/blob/master/speedtest-cli-3#L271 then it should not be hard to do add it.
