* Partial move to ff 0.13 It turns out the newly released k256 0.12 isn't on ff 0.13, preventing further work at this time. * Update all crates to work on ff 0.13 The provided curves still need to be expanded to fit the new API. * Finish adding dalek-ff-group ff 0.13 constants * Correct FieldElement::product definition Also stops exporting macros. * Test most new parts of ff 0.13 * Additionally test ff-group-tests with BLS12-381 and the pasta curves We only tested curves from RustCrypto. Now we test a curve offered by zk-crypto, the group behind ff/group, and the pasta curves, which is by Zcash (though Zcash developers are also behind zk-crypto). * Finish Ed448 Fully specifies all constants, passes all tests in ff-group-tests, and finishes moving to ff-0.13. * Add RustCrypto/elliptic-curves to allowed git repos Needed due to k256/p256 incorrectly defining product. * Finish writing ff 0.13 tests * Add additional comments to dalek * Further comments * Update ethereum-serai to ff 0.13 |

Schnorr Signatures
A challenge (and therefore HRAm) agnostic Schnorr signature library. This is intended to be used as a primitive by a variety of crates relying on Schnorr signatures, voiding the need to constantly define a Schnorr signature struct with associated functions.
This library provides signatures of the R, s form. Batch verification is
supported via the multiexp crate. Half-aggregation, as defined in
https://eprint.iacr.org/2021/350, is also supported.
This library was audited by Cypher Stack in March 2023, culminating in commit 669d2dbffc1dafb82a09d9419ea182667115df06. Any subsequent changes have not undergone auditing.
