Description: Create a blended curve from two survival curves, which is
        particularly useful for survival extrapolation in health
        technology assessment. The main idea is to mix a flexible model
        that fits the observed data well with a parametric model that
        encodes assumptions about long-term survival. The two curves
        are blended into a single survival curve that is identical to
        the first model over the range of observed times and gradually
        approaches the parametric model over the extrapolation period
        based on a given weight function. This approach allows for the
        inclusion of external information, such as data from registries
        or expert opinion, to guide long-term extrapolations,
        especially when dealing with immature trial data. See Che et
        al. (2022) <doi:10.1177/0272989X221134545>.
