Julia array indexing is 1 based
When transpiling, we should convert 0 based indexing to 1 based.

Sample test case:

```
a = [i for i in range(10)]

def foo() -> int:
    sum = 0
    for i in range(10):
        sum += a[i]
    return sum


if __name__ == '__main__':
    print(foo())
```

Should print 45.
