easystats/performance: performance 0.16.0

Breaking Changes model_performance() for psych FA objects now correctly names the metric as RMSR (Root Mean Square Residual) instead of RMSA. The RMSR_corrected column (previously RMSA_corrected) is also renamed accordingly. The first argument in check_model(), check_predictions() and check_convergence() was renamed to model. Changes check_model() now limits the number of data points for models with many observations, to reduce the time for rendering the plot via the maximum_dots argument. check_model() can now show or hide confidence intervals using the show_ci argument. For models with only categorical predictors, confidence intervals are not shown by default. Bug fixes Fixed issue in check_dag() with multiple colliders. Fixed CRAN check issues.
