#' Tukey Honest Significant Differences
#' @description
#' `r badge('experimental')`
#'
#' Helper function to perform Tukey post-hoc tests. It is used in [gafem].
#'
#' @param model an object of class `aov` or `lm`.
#' @param ... other arguments passed to the function
#' [stats::TukeyHSD()]. These include:
#' * **which**: A character vector listing terms in the fitted model for which the
#' intervals should be calculated. Defaults to all the terms.
#' * **ordered**: A logical value indicating if the levels of the factor should be
#' ordered according to increasing average in the sample before taking
#' differences. If ordered is true then the calculated differences in the means
#' will all be positive. The significant differences will be those for which the
#' lwr end point is positive.
#' @param out The format of outputs. If `out = "long"` a 'long' format
#' (tibble) is returned. If `out = "wide"`, a matrix with the adjusted
#' p-values for each term is returned.
#' @md
#' @return A tibble data frame containing the results of the pairwise
#' comparisons (if `out = "long"`) or a "list-columns" with p-values for
#' each term (if `out = "wide"`).
