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

        <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

        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,
