Verification code bug

[skp-github]

The verify function in case of suspected models have a bug.
i.e The length of predictions_reference list will not be equal to the length of pred_suspect (line 526 in marktorch.py)

It's a very small change, i can give a PR if you think the bug is correct.

Hi @skp-github, thank you, you can submit a PR for this. You can modify the beginning of the verify function in verification.py to compare outputs_original and outputs_suspect.
