Description: Survival analysis using a flexible Bayesian model for
        individual-level right-censored data, optionally combined with
        aggregate data on counts of survivors in different periods of
        time. An M-spline is used to describe the hazard function, with
        a prior on the coefficients that controls over-fitting.
        Proportional hazards or flexible non-proportional hazards
        models can be used to relate survival to predictors. Additive
        hazards (relative survival) models, waning treatment effects,
        and mixture cure models are also supported. Priors can be
        customised and calibrated to substantive beliefs. Posterior
        distributions are estimated using 'Stan', and outputs are
        arranged in a tidy format. See Jackson (2023)
