PhysioCrossModal: Cross-Modal Coupling Analysis for PhysioExperiment Objects

Provides cross-modal coupling, connectivity, and synchrony analysis between physiological signals of different modalities (EEG, EMG, ECG, EDA, MoCap, fNIRS, etc.). Introduces a MultiPhysioExperiment container class for holding multiple PhysioExperiment objects at different sampling rates with temporal alignment. Includes spectral coherence, phase synchrony (PLV, PLI, wPLI), directed coupling (Granger causality), and time-domain coupling (cross-correlation) methods.
