Function predict_ensemble 

pub fn predict_ensemble(
    desc: &MolecularDescriptors,
    elements: &[u8],
    bonds: &[(usize, usize, u8)],
) -> EnsembleResult

Predict molecular properties using an ensemble of models.

Combines three LogP models via consensus, adds TPSA, pKa estimates, BBB permeability, and Veber bioavailability rules.
