This PR adds the classic predator-prey time series dataset (
abundance.csv) to the package. Originally compiled in therEDMR package, this dataset is widely adopted as a control benchmark for nonlinear causal discovery methods, particularly Convergent Cross Mapping (CCM) and Empirical Dynamic Modeling (EDM).Dataset Overview
