TidyDensity 1.4.0

Breaking Changes

None

New Features

1. Fix #405 - Add function quantile_normalization() to normalize data using quantiles.
2. Fix #409 - Add function check_duplilcate_rows() to check for duplicate rows in a data frame.
3. Fix #414 - Add function util_chisquare_param_estimate() to estimate the parameters of the chi-square distribution.
4. Fix #417 - Add function tidy_mcmc_sampling() to sample from a distribution using MCMC.
   This outputs the function sampled data and a diagnostic plot.
5. Fix #421 - Add functions util_dist_aic() functions to calculate the AIC for a distribution.

Minor Fixes and Improvements

1. Fix #401 - Update tidy_multi_single_dist() to respect the .return_tibble parameter
2. Fix #406 - Update tidy_multi_single_dist() to exclude the .return_tibble parameter
   from returning in the distribution parameters.
3. Fix #413 - Update documentation to include mcmc where applicable.
4. Fix #240 - Update tidy_distribution_comparison() to include the new AIC calculations
   from the dedicated util_dist_aic() functions.
