Add Ladder function

[jimmyday12]

There should be an easy function to return the AFL ladder for any round. The Squiggle API does a decent job back to round 2011

I have a function that might do this... it takes in a data frame obtained using get_match_results() and can return results from all regular season rounds and all seasons, or be limited to certain round(s) and season(s).

Any interest in this?

[jimmyday12]

@JaseZiv Yep certainly some interest. My initial thoughts were just writing a scraper but your approach could be feasible too and possibly faster since get_match_results() is relatively quick to scrape.

@jimmyday12 Ok great. I've got the function ready so I'll write some docs and create a pull request tomorrow hopefully and you can let me know your thoughts.
