Update carbon control to latest version of Sustainable Web Design Model

[fershad]

Feature Request Summary

The Carbon Control feature currently implements the default carbon estimation model from CO2.js. At the time of writing, this is Sustainable Web Design Model version 3. However, this is an older version of the Sustainable Web Design Model and an updated version (Sustainable Web Design Model version 4 - SWDMv4) has now been released (see docs). This version is also available in CO2.js v0.16 - see release notes.

What's the motivation or use case for the change/feature?

Use a more recent model for carbon estimation.

@fershad quick question on that: we took a look at this and for example ndtv.com moved from 4.8g per visit to 1.55g per visit. Seems reasonable to you?
Also is 0.6 still the top 100 site's median grams per visit?
Thanks
