Description: Provides several methods for computing the Quantile
        Treatment Effect (QTE) and Quantile Treatment Effect on the
        Treated (QTT). The main cases covered are (i) treatment is
        randomly assigned, (ii) treatment is as good as randomly
        assigned after conditioning on covariates (selection on
        observables) using the methods of Firpo (2007)
        <doi:10.1111/j.1468-0262.2007.00738.x>, and (iii)
        identification is based on a Difference in Differences
        assumption, with support for several varieties including Athey
        and Imbens (2006) <doi:10.1111/j.1468-0262.2006.00668.x>,
        Callaway and Li (2019) <doi:10.3982/QE935>, and Callaway, Li,
        and Oka (2018) <doi:10.1016/j.jeconom.2018.06.008>. Version 2.0
        adds a unified staggered treatment adoption API (built on
        'ptetools') for all DiD-based estimators, as well as a new
        lagged-outcome unconfoundedness estimator ('lou_qtt').
