/*!FSE_compressU16() :
   data is presented or regenerated as a table of unsigned short (2 bytes per symbol),

   Important ! All symbol values within input table must be <= 'maxSymbolValue'.
   Maximum allowed 'maxSymbolValue' is controlled by constant FSE_MAX_SYMBOL_VALUE

                    if result == 1, data is one constant element x srcSize times. Use RLE compression.
