Function yarray_iter_next 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn yarray_iter_next(
    iterator: *mut ArrayIter,
) -> *mut YOutput

Moves current YArray iterator over to a next element, returning a pointer to it. If an iterator comes to an end of an array, a null pointer will be returned.

Returned values should be eventually released using youtput_destroy function.
