StartPad with 0

Added '0' padding to 2, 3, and 4 digs ANZSIC and Num Col to Division Alpha to address issue 3 & 4.

Hi @Crow2525-pp, thank you for the PR.

May I get your opinion on whether we should treat those number columns as numeric or character? The reason I'm asking is because all the values in those columns are numeric. Is it better to leave them as they are?

@williamlai2 would this PR affect your code? specifically https://github.com/runapp-aus/strayr?

Looking at https://github.com/runapp-aus/strayr/blob/master/data-raw/create_anzsic2006.R this change would break the code because anzsic_class_code and other bits rely on the group_code in the original file being a double that gets converted to an integer, whereas with the padded 0, they would be strings. This could all be fixed though.

@daviddiviny wrote the original code for this.

It is slightly related to issues in runapp-aus/strayr#91 as well. A workaround could be having a different source for the ANZSIC codes too.

Yes, this is worth fixing I think.

Fixed in #7.
