#' @description
#' Gets a list of `ReferenceSets`.
#'
#' @param con list; required: TRUE; BrAPI connection object
#' @param referenceSetDbId character; required: FALSE; The unique database
#'    identifier of the `ReferenceSet` to be retrieved.
#' @param accession character; required: FALSE; If set, return the reference
#'    sets for which the `accession` matches this string (case-sensitive,
#'    exact match).
#' @param assemblyPUI character; required: FALSE; If set, return the reference
#'    sets for which the `assemblyId` matches this string (case-sensitive, exact
#'    match).
#' @param md5checksum character; required: FALSE; If set, return the reference
#'    sets for which the `md5checksum` matches this string (case-sensitive,
#'    exact match).
#' @param page integer; required: FALSE; Used to request a specific page of data
#'    to be returned. The page indexing starts at 0 (the first page is
#'    `page = 0`). Default is `0`.
#' @param pageSize integer; required: FALSE; The size of the pages to be
#'    returned. Default is `1000`.
