Predict Trait Scores for New Data using a Fitted Stan Model

Extracts posterior means of item parameters from a fitted Stan TIRT model and uses analytical BFGS optimization to instantly score new respondents.

predict_tirt_stan(fit, stan_data, new_pairwise_data)

`fit`	A fitted model object from either cmdstanr or rstan.
`stan_data`	The original data list passed to Stan (used to map the test design).
`new_pairwise_data`	A dataframe of pairwise binary responses for the NEW respondents.
