Consider adding NOAA Project EAGLE ensemble model

[williamhobbs]

I just saw that a Graphcast ensemble from NOAA Project EAGLE is available. I don't think it's in Herbie.

Global-EAGLE-Ensemble via NODD: https://noaa-nws-graphcastgfs-pds.s3.amazonaws.com/index.html#EAGLE_ensemble/.

Note that there's also Global-EAGLE-Solo, but I think that's the GFS Graphcast model that's already in Herbie. See the "Get data" column in the table on this page, https://www.epic.noaa.gov/ai/eagle-ensemble-configuration/.

Heard about this via https://www.linkedin.com/posts/ryanmaue_noaa-has-quietly-launched-project-eagle-into-activity-7395488846274265088-RttQ.
