demofit: Parametric Mortality Curve Fitting and Mortality Forecasting Tools

Provides tools for fitting parametric mortality curves. Implements multiple optimisation strategies to enhance robustness and stability of parameter estimation. Offers tools for forecasting mortality rates guided by mortality curves.
