分类效应修饰因素的 one-hot 编码破坏了 EconML 的效应估计

Description When using an EconML estimator through DoWhy with a categorical variable specified as an effect modifier, DoWhy one-hot encodes the effect modifier internally and changes its column name. However, the subsequent call to EconMLEstimator.effect() still attempts to access the effect modifier using its original column name.
