#' Get FN127 - Age data from FN_Portal API
#'
#' This function accesses the api endpoint to for FN127 - age
#' estimate/interpretations.  This function takes an optional filter
#' list which can be used to return records based on several
#' different attributes of the age estimate such as the assigned age,
#' the aging structure, confidence, number of complete annuli and
#' edge code, or whether or not it was identified as the 'preferred'
#' age for this fish. Additionally, filters can be applied to
#' select age estimates based on attributes of the sampled fish such
#' as the species, or group code, or attributes of the effort, the
#' sample, or the project(s) that the samples were collected in.
#'
#' Use \code{show_filters("fn127")} to see the full list of available
#' filter keys (query parameters). Refer to
#' \url{https://intra.glis.mnr.gov.on.ca/fn_portal/api/v1/swagger/}
#' and filter by "fn127" for additional information.
#'
#' @param filter_list list
#' @param show_id When 'FALSE', the default, the 'id' and 'slug'
#' fields are hidden from the data frame. To return these columns
#' as part of the data frame, use 'show_id = TRUE'.
#' @param to_upper - should the names of the dataframe be converted to
#' upper case?
