Fix some FROST nits (#63) 
* Impl DefaultIsZeros for every type that uses jubjub::Fr/Scalar

This requires Copy and Clone along with Default. If we do not want to include those, we can impl Zeroize and Drop directly.

* Hash signature message with HStar before deriving the binding factor

To avoid a collision, we should hash our input message, our 'standard' hash is HStar, which uses a domain separator already, and is the same one that generates the binding factor.

* Add a comment about why we hash the signature message before generating the binding factor

* Add comments on how we Zeroize

* Consume nonces with sign()

We want to make sure that the nonces we use when signing are Drop'd
(and thus Zeroize'd) when they go out of scope, so we must move participant_nonces into sign()

Frost keygen with dealer (#47) 
Implements FROST (Flexible Round Optimized Schnorr Threshold Signatures, https://eprint.iacr.org/2020/852) where key generation is performed by a trusted dealer. 

Future work will include implementing distributed key generation and re-randomizability.

Add batch::Item::verify_single and Item: Clone + Debug. (#39) 
This closes a gap in the API where it was impossible to retry items in a failed
batch, because the opaque Item type could not be verified individually.

Henry de Valence d8ad15059d Try to prevent ChangePubkey tweaks from becoming a no-op. 
Since we expect the signature to fail if ChangePubkey is applied, we need to
make sure it actually changes the signature test case.
