functions that made me love the package was at_depth, which iterates across a
list at a specified level of nesting. It has since been deprecated in favor of

map_dfc for row and column binding, respectively) to iterate over a list à la
lapply and simplify the result to a data frame. Thanks to the power of
dplyr::bind_rows, it fixes all the drawbacks of sapply’s simplify2array
