sitespeed.io 21.3.0 on Node.js NPM

21.3.0 - 2022-01-01

Updated to Browsertime 14.13.0 with the following fixes for the user agent:
- Append text to Chrome/Edge user agent using --chrome.appendToUserAgent
- When you use Chrome/Edge and use a "emulated device" that will use the user agent that you provide using --userAgent. Else it will use the user agent from your emulated device setting.
- You can also use Edge to run emulated mobile with the same settings as Chrome.
