Description
Currently weight_draws(x, weights, ...) requires weights to be a numeric vector. Would it be possible to have a piping version so that when the draws object already has a variable that contains the log weights e.g. named lw, we could pipe
x <- x |> mutate_varibles(lw = lp__-lp_approx__) |> weight_draws(weights=lw, log=TRUE)
and even better if we can pipe as
x <- x |> weight_draws(weights=lp__-lp_approx__, log=TRUE)
Piping resample_draws would also be useful (with added option for log) so that we could skip the weight_draws
x1 <- x |> resample_draws(weights=lp__-lp_approx__, log=TRUE, ndraws=1)

Research direction
Start by reading the existing weight_draws and resample_draws implementations and their current weight-handling interfaces. The work is done when the requested piping forms support weights stored in the draws object, log weights, and resampling with ndraws as shown in the examples.
