Calculates the Bayesian Information Criterion (BIC) which is a
trade-off between goodness of fit (measured in terms of
log-likelihood) and model complexity (measured in terms of number
of included features).
Internally, stats::BIC() is called.
Requires the learner property "loglik", NA is returned for unsupported learners.
