Update the type-1 met corrections to the new CMS recommendations once the metfactory has been updated in Coffea. They have implemented it in the dev branch a few days ago, so we will need to update from Coffea 2025.1.1 to the latest stable version once they have it working.
The updated recommendations are here:
https://cms-jerc.web.cern.ch/Type1MET/
It involves using the RawPuppiMET and the CorrT1MetJet collections. I tried to do the implementation of the corrections with what we already have, but we are unable to do Step 2 under section 1.5 (as the updating of the met components jet-by-jet is done within the met-factory).
If we do not want to update the Coffea version, I can implement it by hand. The looping over the jets and updating the met components will not be too involved/difficult.
New Coffea changes:

Shout out to Maria Mazza for bringing this to my attention!
