Formula: I_t = R_t sum_{tau=1}^{gmax} g(tau) I_{t-tau}, so R_t = I_t / sum_tau g(tau) I_{t-tau}

Abbott, Hellewell, Sherratt et al (2020), EpiNow2. Model definition verified against the package's own estimate_infections() vignette, which states I_t = R_t sum_tau g(tau) I_{t-tau} and the delay convolution D_t = xi sum_tau xi(tau) I_{t-tau}.
