Description: Estimate average treatment effects (ATEs) in stratified
        randomized experiments. 'sreg' supports a wide range of
        stratification designs, including matched pairs, n-tuple
        designs, and larger strata with many units — possibly of
        unequal size across strata. 'sreg' is designed to accommodate
        scenarios with multiple treatments and cluster-level treatment
        assignments, and accommodates optimal linear covariate
        adjustment based on baseline observable characteristics. 'sreg'
        computes estimators and standard errors based on Bugni, Canay,
