Inference seems to kind of work, but it produces oversaturated images even at low CFG. I'm not entirely sure what's the problem. It's really hard to find any information about what the "Cosine-Continuous EDM VPred schedule" is supposed to be exactly, if anyone has insight, please do share.

(CosXL edit works when this is combined with #679, but it has the same oversaturation issues as regular CosXL)

Fixes #630

Hmm it looks like the --schedule argument has no effect, maybe this can be related to those artifacts...
