function used internally by rsdmx, when loading the package, to set the list of SDMXServiceProvider known by rsdmx (hence known by readSDMX to query data/metadata in an easier way). For internal use only (this function does not provide any value for the end user, but it is here documented for transparency, and to explain how the package works.)
