Print Method for survfit_fast Objects

Formats and prints a survfit_fast object similarly to print(summary(survival::survfit(...), times = t_eval)), showing the Kaplan-Meier survival estimate, the Greenwood standard error on the survival scale, and the confidence interval at the requested evaluation time.
