Description: Computes predicted values and lower/upper limits of normal
        for pulmonary function tests according to American Thoracic
        Society (ATS) and European Respiratory Society (ERS) reference
        standards. Supports spirometry (Global Lung Function Initiative

        interpretive pattern labels (Normal, Non-specific, Obstructed,
        Restricted, Mixed) from spirometry and lung-volume measurements
        following the ERS/ATS 2022 interpretation algorithm, Stanojevic
