FROST Ed448 (#107) * Theoretical ed448 impl * Fixes * Basic tests * More efficient scalarmul Precomputes a table to minimize additions required. * Add a torsion test * Split into a constant and variable time backend The variable time one is still far too slow, at 53s for the tests (~5s a scalarmul). It should be usable as a PoC though. * Rename unsafe Ed448 It's not only unworthy of the Serai branding and deserves more clarity in the name. * Add wide reduction to ed448 * Add Zeroize to Ed448 * Rename Ed448 group.rs to point.rs * Minor lint to FROST * Ed448 ciphersuite with 8032 test vector * Macro out the backend fields * Slight efficiency improvement to point decompression * Disable the multiexp test in FROST for Ed448 * fmt + clippy ed448 * Fix an infinite loop in the constant time ed448 backend * Add b"chal" to the 8032 context string for Ed448 Successfully tests against proposed vectors for the FROST IETF draft. * Fix fmt and clippy * Use a tabled pow algorithm in ed448's const backend * Slight tweaks to variable time backend Stop from_repr(MODULUS) from passing. * Use extended points Almost two orders of magnitude faster. * Efficient ed448 doubling * Remove the variable time backend With the recent performance improvements, the constant time backend is now 4x faster than the variable time backend was. While the variable time backend remains much faster, and the constant time backend is still slow compared to other libraries, it's sufficiently performant now. The FROST test, which runs a series of multiexps over the curve, does take 218.26s while Ristretto takes 1 and secp256k1 takes 4.57s. While 50x slower than secp256k1 is horrible, it's ~1.5 orders of magntiude, which is close enough to the desire stated in https://github.com/serai-dex/serai/issues/108 to meet it. Largely makes this library safe to use. * Correct constants in ed448 * Rename unsafe-ed448 to minimal-ed448 Enables all FROST tests against it. * No longer require the hazmat feature to use ed448 * Remove extraneous as_refs
