[AUTOMATED] Update average annual grid intensities f59eefc

Please note that this update includes data from Ember Climate that reflects their updated carbon intensity methodology.

Read the methodology at: https://ember-climate.org/data-catalogue/yearly-electricity-data/

A note from Ember about the change is below:

We have made a significant update to our carbon intensity calculations which hopefully helped to significantly increase their accuracy. Previously, we were using IPCC emissions factors by fuel that did not distinguish between countries or technologies. Our new factors are on a by country, by fuel, by year basis to more accurately capture coal and gas fleets, how they change over time, and where and how coal and gas is sourced.

Crucially, while widely used, IPCC factors were a significant underestimate, especially for emissions from coal generation. The IPCC, in its methodology, relied on calculations that assumed near impossible efficiency for future coal plants that does not accurately reflect current day coal generation.

We hope that our new approach will be more accurate and we're aiming to make our methodology fully public and reproducible in the near future.

co2.js - v0.14.1

Why not v0.14.0? Because about 6 months ago I accidentally published v0.14.0 instead of a patch version update. I couldn't remove the tags from NPM or unpublish the package, so we're here now.

⚠️ Upcoming feature deprecation notice

In the next version of CO2.js (0.15.0) we will be removing some functions that were specific to using CO2.js with Sitespeed's Page X-ray. Namely, we will be removing the following functions from the CO2.js library:

perDomain
perPage
perContentType
dirtiestResources
perParty

This functionality has already been merged into the Sitespeed.io Sustainability Plugin. Once the above functions have been removed from CO2.js, you will need to use the Sitespeed.io Sustainability Plugin or your own code for that functionality.

If this change impacts your code, please follow the issue on GitHub and leave a comment if you have any concerns.
