Can we be sure that crypto/ed25519 performs exactly the same malleability checks as ed25519-dalek verify_strict?

We should probably add test fixtures for edge cases.

According to the post, this Go package does malleability checks: https://github.com/hdevalence/ed25519consensus

Haven't found any information on what the current status of the stdlib implementation is.

I'm not sure if it actually matters for transaction verification outside of consensus use cases.
