Description: Estimates the time-varying reproduction number, rate of
    spread, and doubling time using a renewal equation approach combined
    with Bayesian inference via Stan. Supports Gaussian process and
    random walk priors for modelling changes in
    transmission over time. Accounts for delays between infection and
    observation (incubation period, reporting delays), right-truncation
    in recent data, day-of-week effects, and observation overdispersion.
    Can estimate relationships between primary and secondary outcomes
    (e.g., cases to hospitalisations or deaths) and forecast both. Runs
    across multiple regions in parallel. Based on
    Abbott et al. (2020) <doi:10.12688/wellcomeopenres.16006.1> and
    Gostic et al. (2020) <doi:10.1101/2020.06.18.20134858>.
