o-rating and d-rating

[jakeakopp]

Hi. I was looking for a way to gather per-game O and D ratings and with the patch your tool seems to do the trick!

It would also be pretty easy to add support for the other "advanced" stats using this approach.

FWIW I want this for an idea I have to calculate opponent-adjusted ratings to do things like compensate for strength of schedule or reduce the amount of credit given for running up the score on the worst teams.

@jakeakopp thanks for opening this PR (and sorry for the massive delay in getting back to you).

Just so I understand the intent - were you looking to add advanced team statistics for data rendered by specific box score pages like: https://www.basketball-reference.com/boxscores/201810160BOS.html ?

If so, were you looking to add the data from the set of data tables outlined in the image below?

+1 for this, this would be a very useful feature when looking at individual box scores. Some stats like True Shooting % and EFG % are easy to calculate from the basic box score. But other advanced stats like box plus minus are nearly impossible to calculate. Everything to the right of free throw attempt rate would honestly be nice to include.
