Merge pull request #153 from huitseeker/non_repudiation 
[test-only] Add test showing non-repudiation for verify, verify_strict

Implements an Elligator2 map for Curve25519 
This implementation:
- is agnostic on the hash used to pick a field element, even though SHA512 is commonly used,
- follows https://tools.ietf.org/id/draft-irtf-cfrg-hash-to-curve-10.html closely
- tests the outputs of the function using libsignal's implementation.

`println!` was removed in the test as the corresponding test for `u32` does not have it.

[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.

Fix serde implementation for serde_json 
We use the [serde_bytes](https://github.com/serde-rs/bytes) crate for
serialization implementations, which simplifies codes and fixes issues
for serde_json.

2408e6b179 Update curve25519-dalek to version 3.0.0. 
This allows unifying dependencies with other crates using the `3.x` series of
the curve library.  It is a semver patch-level change, because the x25519-dalek
API does not expose any details of the underlying curve implementation.
