Transcript crate with both a merlin backend and a basic label len value backend Moves binding factor/seeded RNGs over to the transcripts.

[package]
Rename transcript-trait to flexible-transcript It offers the trait for flexibility, yet it also offers an incredibly competent (and logical) transcript format, along with a Merlin wrapper.

name = "flexible-transcript"
Use std-shims to reduce flexible-transcript MSRV to 1.66 flexible-transcript already had a shim to support <1.66. This was irrelevant since flexible-transcript had a MSRV of 1.73. Due to how clunky it was, it has been removed despite theoretically enabling an even lower MSRV.

Replace `Ciphersuite::hash_to_F` The prior-present `Ciphersuite::hash_to_F` was a sin. Implementations took a DST, yet were not require to securely handle it. It was also biased towards the requirements of `modular-frost` as `ciphersuite` was originally written all those years ago, when `modular-frost` had needs exceeding what `ff`, `group` satisfied. Now, the hash is bound to produce an output which can be converted to a scalar with `ff::FromUniformBytes`. A new `hash_to_F`, which accepts a single argument of the value to hash (removing the potential to insecurely handle the DST by removing the DST entirely). Due to `digest` yielding a `GenericArray`, yet `FromUniformBytes` taking a `const usize`, the `ciphersuite` crate now defines a `FromUniformBytes` trait taking an array (then implemented for all satisfiers of `ff::FromUniformBytes`). In order to get the array type from the `GenericArray`, the output of the hash, `digest` is updated to the `0.11` release candidate which moves to `flexible-array` which solves that problem. The existing, specific `hash_to_F` functions have been moved to `modular-frost` as necessary. `flexible-array` itself is patched to a fork due to https://github.com/RustCrypto/hybrid-array/issues/131.

[dependencies]
Add no_std support to transcript, dalek-ff-group, ed448, ciphersuite, multiexp, schnorr, and monero-generators transcript, dalek-ff-group, ed449, and ciphersuite are all usable with no_std alone. The rest additionally require alloc. Part of #279.

zeroize = { version = "^1.5", default-features = false }
Resolve #268 by adding a Zeroize to DigestTranscript which writes a full block This is a 'better-than-nothing' attempt to invalidate its state. Also replaces black_box features with usage of the rustversion crate.

Smash the singular `Ciphersuite` trait into multiple This helps identify where the various functionalities are used, or rather, not used. The `Ciphersuite` trait present in `patches/ciphersuite`, facilitating the entire FCMP++ tree, only requires the markers _and_ canonical point decoding. I've opened a PR to upstream such a trait into `group` (https://github.com/zkcrypto/group/pull/68). `WrappedGroup` is still justified for as long as `Group::generator` exists. Moving `::generator()` to its own trait, on an independent structure (upstream) would be massively appreciated. @tarcieri also wanted to update from `fn generator()` to `const GENERATOR`, which would encourage further discussion on https://github.com/zkcrypto/group/issues/32 and https://github.com/zkcrypto/group/issues/45, which have been stagnant. The `Id` trait is occasionally used yet really should be first off the chopping block. Finally, `WithPreferredHash` is only actually used around a third of the time, which more than justifies it being a separate trait. --- Updates `dalek_ff_group::Scalar` to directly re-export `curve25519_dalek::Scalar`, as without issue. `dalek_ff_group::RistrettoPoint` also could be replaced with an export of `curve25519_dalek::RistrettoPoint`, yet the coordinator relies on how we implemented `Hash` on it for the hell of it so it isn't worth it at this time. `dalek_ff_group::EdwardsPoint` can't be replaced for an re-export of `curve25519_dalek::SubgroupPoint` as it doesn't implement `zeroize`, `subtle` traits within a released, non-yanked version. Relevance to https://github.com/serai-dex/serai/issues/201 and https://github.com/dalek-cryptography/curve25519-dalek/issues/811#issuecomment-3247732746. Also updates the `Ristretto` ciphersuite to prefer `Blake2b-512` over `SHA2-512`. In order to maintain compliance with FROST's IETF standard, `modular-frost` defines its own ciphersuite for Ristretto which still uses `SHA2-512`.

Correct std feature-flagging If a crate has std set, it should enable std for all dependencies in order to let them properly select which algorithms to use. Some crates fallback to slower/worse algorithms on no-std. Also more aggressively sets default-features = false leading to a *10%* reduction in the amount of crates coordinator builds.
