Add fuel-specific EIA-923 allocation warning

[grgmiller]

After running the EIA-923 allocation, we currently check whether the total plant-level generation and fuel matches the input data. However, we should also check for each fuel consumed at the plant that the totals match. This would protect us if certain fuels are getting dropped from the pipeline.

This was inspired by looking at plant 50900 in 2020, which had some fuels dropped from the output. This seems to have been fixed with the new data, but something that should have been caught.
