sprtt 0.3.0

• Add: plan_sample_size() creates HTML reports for sample size planning of sequential ANOVAs

• Add: download_sample_size_data() downloads the data required for plan_sample_size()

• Add: load_sample_size_data() provides manual access to the simulation dataset used by plan_sample_size()

• Add: cache_clear() removes the cached simulation dataset used by plan_sample_size()

• Add: cache_info() displays information about cached simulation data used by plan_sample_size()

• Breaking change: plot_anova() argument position_lr_x now uses absolute x-axis coordinates (e.g., position_lr_x = 30 places the label at x = 30) instead of relative positioning, providing more intuitive and precise control of label placement.

• Add: plot_anova() gains new argument position_lr_y to control the y-axis position of the likelihood ratio label using absolute coordinates.

• Change: Internal function documentation improved throughout the package
