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
    'GLI' 2012, Quanjer et al. (2012) <doi:10.1183/09031936.00080312>;
    and the race-neutral 'GLI' 2022 / 'GLI Global' equations, Bowerman
    et al. (2023) <doi:10.1164/rccm.202205-0963OC>), static lung
    volumes ('GLI' 2021, Hall et al. (2021)
    <doi:10.1183/13993003.00289-2020>), and the carbon monoxide
    transfer factor / diffusion capacity ('GLI' 2017, Stanojevic et al.
    (2017) <doi:10.1183/13993003.00010-2017>, including the 2020
    author correction <doi:10.1183/13993003.50010-2017>). Also assigns
    interpretive pattern labels (Normal, Non-specific, Obstructed,
    Restricted, Mixed) from spirometry and lung-volume measurements
    following the 'ERS'/'ATS' 2022 interpretation algorithm,
