#' Progressively
#'
#' This function helps add progress-reporting to any function - given function `f()` and progressor `p()`, it will return a new function that calls `f()` and then (on-exiting) will call `p()` after every iteration.
#'
#' This is inspired by purrr's `safely`, `quietly`, and `possibly` function decorators.
#'
#' @param f a function to add progressr functionality to.
#' @param p a progressor function as created by `progressr::progressor()`
#' @keywords Internal
#'
#' @return a function that does the same as `f` but it calls `p()` after iteration.
