rsetienne/DAISIE: v4.0.5

DAISIE 4.0.5 N.B.: MacOS users may experience issues when installing DAISIE, especially when on MacOS Big Sur. If that is you case, please see here for detailed installation instructions. CS model can be fit with C++ code, similarly to the IW model since version v3.2.0. To do so, set methode to: "odeint::runge_kutta_cash_karp54" "odeint::runge_kutta_fehlberg78" [default] "odeint::runge_kutta_dopri5" "odeint::bulirsch_stoer" without the odeint::-prefix, the deSolve::ode method is assumed. deSolve::ode using "lsodes" is still the default, as before. Make sure CS_version = 0 (default) to use C++ ODEINT numerical integration. Better handling of number of threads to use with DAISIE_IW_num_threads() for ML estimation of the IW model when more threads are available. Fixes to numerical instability in conditional probability calculation in the IW model when the probability of extinction is very close to 1. Introduce an approximation when the log conditional likelihood cannot be computed and add message when this is triggered
