This reworks the API to make KeyGen::from_seed return a `SeededSigningKey` instead of a `KeyPair`. The `SeededSigningKey` effectively replaces the `KeyPair`, and instead of eagerly generating the VerifyingKey (implementing `signature::KeypairRef`), it implements `signature::Keypair` and makes the verifying key when requested. This reduces the depth of the stack when calling from_seed and reduces the size of the stack by 207kb using ML-DSA-87 in debug/tests builds (the heaviest consumers). This is an API break.
RustCrypto: Signatures 
Support for digital signatures, which provide authentication of data using public-key cryptography.
All algorithms reside in the separate crates and implemented using traits from
the signature crate.
Crates are designed so they do not require the standard library (i.e. no_std)
and can be easily used for bare-metal or lightweight WebAssembly programming.
Crates
NOTE: for RSA signatures see https://github.com/RustCrypto/RSA
Usage
Crates functionality is expressed in terms of traits defined in the signature
crate.
License
All crates licensed under either of
