compute_stats: General Quantitative Function
In Scott-Coggeshall/magictable:

compute_quant provides the most general and flexible way of specifying the quant_func argument to survey_table.

1	compute_stats(x, stat_func, stat_args, labels = NULL)

`x`	a numeric vector
`labels`	a vector of character strings giving the labels for the elements of the output. Default is to use `func_names`.
`func_names`	a vector of character strings giving the names of the functions to be applied to `x`.
`func_args`	a list with number of elements equal to `length(func_names)`. Each element of `func_args` should itself be a named list of arguments to be passed to the corresponding element of `func_names`. If the list consists of non-list elements, then it is assumed that this single list contains arguments that should be applied to all functions contained in `func_names`.
