Http2 downloads are super slow

[kanongil]

Describe the bug

• Node.js version: v14.14.0
• OS & version: macOS 10.15.7

Http2 downloads are horrendously slow due to nodejs/node#31084, with no workaround.

Note: the actual transfer speed will vary drastically depending on your link speed and the RTT to the server.

Actual behavior

Super slow transfer: default: 48.537s

Expected behavior

Something matching the http2: false speed, which returned: default: 10.923s

Code to reproduce

const Got = require('got');

(async () => {

    console.time();
    await Got.get('https://mirror.leaseweb.com/speedtest/100mb.bin', { http2: true });
    console.timeEnd();
})();

Checklist

• I have read the documentation.
• I have tried my code with the latest version of Node.js and Got.

@szmarczak Won't your update crash on node 14? You unconditionally call a non-existing API in your patch.

[szmarczak]

Got throws if you're trying to run HTTP/2 on Node.js lower than 15.

So no, it doesn't crash because it doesn't call that function.
