speedtest is discontinued

[snaeil]

The referenced https://github.com/sivel/speedtest-cli utility became a public archive recently.

Since it seems discontinued/unmaintained, it might be a good idea to drop support for it?

I'm looking into using https://github.com/cloudflare/networkquality-rs as a drop-in replacment.
