Get item difficulties from a single model or list of models

get_item_diffs(model_ob, single_df = TRUE)

`model_ob`	The fitted model or list of fitted models
`single_df`	Should a single data frame be returned? Defaults to `FALSE`, in which case a list of data frames is returned (assuming) `model_ob` is a list of models. Otherwise a single data frame is returned, which may be generally useful, but is less useful when passing the results to other functions in the package.
