Module batch

Performs batch decaf377-rdsa signature verification.

Batch verification asks whether all signatures in some set are valid, rather than asking whether each of them is valid. This allows sharing computations among all signature verifications, performing less work overall at the cost of higher latency (the entire batch must complete), complexity of caller code (which must assemble a batch of signatures across work-items), and loss of the ability to easily pinpoint failing signatures.

Structs
