Add Odds Ratio and other estimands for AIPTW and TMLE

[pzivich]

Currently AIPTW only returns RD and RR. TMLE returns those and OR as well. I should add support for OR with AIPTW (even though I am not a huge fan of OR when we have nicer estimands)

I should also add support for all / none, and things like ATT and ATU for TMLE and AIPTW both. Basically I need to look up the influence curve info in the TMLE book(s)
