Implement metrics from fault-based-analysis paper #12

It would be nice to implement the metrics used by "Fault Analysis-based Logic Encryption".

Theu use the number of test patterns that have an impact (NoP), times the total number of error (NoO), separated between 0 and 1 fault. This does not really make sense as it creates a quadratic version of the corruption (NoO only), but would be nice to have to compare to.

There are two similar metrics here : FLL from "Fault Analysis-Based Logic Encryption" and KIP from "Hardware Trust: Design Solutions for Logic Locking". Both should have similar behaviour, but the first relies on the number of errors while the second uses output value probabilities.
