IndexError: list index out of range (preprocessor_directive.py)

Been getting this error since the last update (this is taken from the VS Code console):

Traceback (most recent call last):

IndexError: list index out of range

42-c-format: Please read README and check requirements.

File contents:

int main(int argc, char*argv[]){
    return 0;
}

The issue is solved if at least one pre-processor directive is present. Seems like the issue is that indented might be empty, and the code doesn't check for that. So indented[-1] fails.

Would also be nice to add a new test case for pre-processor directives formatter: if no directives are present, do nothing and shouldn't fail

Fixed with #47.
