Get the byte data in the #GBytes. This data should not be modified.
This function will always return the same pointer for a given #GBytes.
%NULL may be returned if @size is 0. This is not guaranteed, as the #GBytes
may represent an empty string with @data non-%NULL and @size as 0. %NULL will
not be returned if @size is non-zero.
