We use Ember's yearly average per region (ember/ember_co2_intensity.csv). Ember also publishes monthly figures, https://files.ember-energy.org/public-downloads/monthly_full_release_long_format.csv (and a separate file per US state), so we could pick the value for the month of the usage, like we do for PUE / WUE since #271.
Monthly data is missing for a few countries we have regions in (Bahrain, Indonesia, Israel, Saudi Arabia, UAE) and lags by 2-3 months, so fall back to the yearly figure when a month is not there.
Needs a change to scripts/fetch_ember_co2_intensity.sh to pull the monthly file as well.
Gets us halfway to #6 without an API key.
