Add accessor to CausalModel._estimator_cache

Thanks for the suggestion @drawlinson . Currently, you can access the estimator after each estimate_effect call.

effect = model.estimate_effect(...)
effect.estimator # returns the fitted CausalEstimator estimator object

Does the above code provide one way to address the issue? That said, I do see the convenience and clarity of your proposal for the end-user. It can be used to compare the different estimators on the same causal model. Feel free to issue a PR and I can review.

I hadn't spotted the estimator object there! In fact I'd used that in the past, I just forgot about it. I will make a PR but the method you've pointed out does solve the problem, so the change I'm proposing is only a convenience.

If this is added, I could also modify an example to extract model coefficients and show how we can explore them in a plot.
