SDL_ReadS64BE - Use this function to read 64 bits of big-endian data from an SDL_IOStream and return in

       This function is available since SDL 3.2.0.

       SDL byteswaps the data only if necessary, so the data returned will be in the native byte order.

       This function will return false when the data stream  is  completely  read,  and  SDL_GetIOStatus()  will
       return  SDL_IO_STATUS_EOF.   If  false  is  returned and the stream is not at EOF, SDL_GetIOStatus() will
       return a different error value and SDL_GetError() will offer a human-readable message.
