#' Get FBref advanced match stats

#' Returns data frame of selected statistics for each match, for either whole team or individual players.
#' Multiple URLs can be passed to the function, but only one `stat_type` can be selected.
#' Replaces the deprecated function get_advanced_match_stats()

#' @param match_url the three character country code for all countries
#' @param stat_type the type of team statistics the user requires
#' @param team_or_player result either summarised for each team, or individual players
#' @param time_pause the wait time (in seconds) between page loads
