Description: A fast and flexible implementation of Callaway and
        Sant'Anna's (2021)<doi:10.1016/j.jeconom.2020.12.001> staggered
        Difference-in-Differences (DiD) estimators, 'fastdid' reduces
        the computation time from hours to seconds, and incorporates
        extensions such as time-varying covariates and multiple events.
