Description: Creates spatially or environmentally separated, or
        group-preserving, training and testing folds for k-fold,
        leave-group-out, and leave-one-out cross-validation. Provides
        spatial blocking, clustering, buffering, and nearest-neighbour
        distance-matching methods, together with tools to visualise
        folds, summarise fold sizes and class balance, and assess
        train–test separation and environmental novelty. Also estimates
        spatial autocorrelation ranges in point samples and continuous
        raster covariates to provide an initial distance scale for
        designing spatial folds. Methods are described in Valavi, R. et
        al. (2019) <doi:10.1111/2041-210X.13107>.
