Description: Implements Transmission Channel Analysis (TCA) for structural
    vector autoregressive (SVAR) models following the methodology of
    Wegner, Lieb, Smeekes and Wilms (2025) <doi:10.48550/arXiv.2405.18987>.
    TCA decomposes impulse response functions (IRFs) into contributions
    from distinct transmission channels using a systems form representation
    and directed acyclic graph (DAG) path analysis. Supports overlapping channels,
    exhaustive 3-way and 4-way decompositions via inclusion-exclusion
    principle. This is a parallel R implementation of the
    'tca-matlab-toolbox' (<https://github.com/enweg/tca-matlab-toolbox>).
