#' Get FN121_Weather - Weather data from FN_Portal API
#'
#' This function accesses the api endpoint for fn121weather
#' records. fn121weather records contain air temperature,
#' precipitation, wind speed and direction, cloud cover, and wave
#' height data collected at time/location 0 and/or 1. Other relevant
#' details for each SAM are found in the FN121 table. This function
#' takes an optional filter list which can be used to return records
#' based on attributes of the SAM including site depth, start and end
#' date and time, effort duration, gear, and location as well as
#' attributes of the projects they are associated with such as project
#' code, or part of the project code, lake, first year, last year,
#' protocol, etc. This function can also take filters related to
#' weather.
#'
#' Use \code{show_filters("fn121weather")} 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 "fn121weather" for additional information.
#'
#' @param filter_list list
#' @param with_121 When 'FALSE', the default, only the weather fields
#' from the FN121 table are returned. To return the whole FN121 table
#' (excluding limnology, trapnet, and trawl fields), use 'with_121 = TRUE'.
#' @param show_id When 'FALSE', the default, the 'slug'
#' field is hidden from the data frame. To return this field
#' as part of the data frame, use 'show_id = TRUE'.
#' @param to_upper - should the names of the dataframe be converted to
#' upper case?
