Scorecard PDO Scaling

Problem

Convert odds to a scorecard score using points to double the odds: factor = pdo / ln(2), offset = base_score - factor * ln(base_odds), score = offset + factor * ln(odds).

Return 0.0 if odds or base_odds is not positive.

Hint

Doubling the odds should add exactly PDO points to the score.
