François Garillot da6c7e114f [test-only] Add test showing the non-repudiation property of the signature verifications used in PublicKey::verify and PublicKey::verify_strict. ... This PR is a follow-up of #98, which aims to demonstrate the issue brought by small-order public keys. It shows an example of crafting a (public_key, signature) that verifies against two distinct messages using `verify`, but fails using `verify_strict`. This has consequences on the possibility to repudiate a signed contract of blockchain transactions.
