Add partial FIG2 label support
Add support for Ensemble label, programme services and components, although the implementation for the component label is not properly tested. (data services still to be done) Neither short labels nor UCS-2 are not yet implemented. Also, support for draftETSI TS 103 176 which redefines the meaning of Rfa is still pending.
