@jdebacker. This PR is spinning out because we need to first merge in PR #73, which fixes the treatment of rho and surv_rate.

@jdebacker. I think this PR is ready for your review and subsequent merge if you think it is ready. It is still not passing the two Windows GH Action CI tests (those tests aren't even starting). This is similar to the previous PR and is an issue we need to resolve. But I think we can merge this in if you think it is ready.

@rickecon These are some great additions here! Everything looks good to me and I'm merging. Looking forward to seeing ogusa on PyPI.
