Unresolved resonance probability table sampling

Unresolved resonance probability table sampling is not used in Serpent by default. This method is needed to account for self-shielding effects in the unresolved resonance region. The effect is usually not significant in thermal systems, but can lead to noticeable discrepancies in fast-spectrum systems.

Probability table sampling is switched on using the set ures option.
