OSBYTE &9B (155) - Write to Video ULA palette register and RAM copy

   This call writes X to the Video ULA palette register and updates
   the RAM copy. The RAM copy is of little use as there are 16 entries
   in the Video ULA palette and the RAM copy will only hold the last
   value written to it. The RAM copy of the palette is in the VDU
   workspace at &035F-&037E.
   Electron OS:
   Completely ignored, performing an RTS immediately
