Implements head movement compensation via SSS. Equivalent to MNE-Python's mne.preprocessing.maxwell_filter with head_pos parameter.

Approach: For each time window, compute the SSS basis at the actual head position, project data into multipole space, then reconstruct at the reference head position.
