Update version to 2.0.2 and document the CallawaySantAnna SE computation fix that now exactly matches R's did package. The weight influence function (wif) formula was corrected to use n_g / n_all for pg computation and iterate over keepers with individual ATT(g,t) values, reducing SE difference from ~2.5% to <0.01% vs R.
