Supervised sleep baselines (SHHS fold 0)

Supervised sleep-staging baselines used by the NeuroAtlas benchmark, fold 0 of SHHS.

These are not redistributions of the public CoRe-Sleep release: that repository
publishes a later code revision whose checkpoints name their class tokens per
modality (cls_token_eeg / cls_token_eog) and do not load into this wrapper.
The file here is the exact checkpoint the paper's numbers were produced with.

stft_norm_eeg.npz holds the per-bin STFT mean and std (129 bins each) that the
CoRe-Sleep wrapper normalises with; it is not optional.
