get_honestdid_obj_did2s

a helper function that takes a fixest feols object (likely
from <code>did2s</code>) that plugs into <code>honest_did</code>. Note this function assumes
the event study coefficients are using <code>i()</code> syntax, e.g. <code>i(rel_year)</code>.
This should also work for a TWFE event-study model estimated by <code>feols</code>.

Estimates Two-way Fixed Effects difference-in-differences/event-study models using the approach proposed by Gardner (2021) <doi:10.48550/arXiv.2207.05943>. To avoid the problems caused by OLS estimation of the Two-way Fixed Effects model, this function first estimates the fixed effects and covariates using untreated observations and then in a second stage, estimates the treatment effects.
