This PR defines and implements a new linked data signature suite (proof type and verification method type) using Aleo keypairs and signatures. A partial specification for the suite is added in the Rust docs, which can be seen rendered in the docs preview links below. A verifiable credential using this signature suite is added as a test vector.
This implementation uses snarkVM crates for the signing and verification functions, types, and global static parameters.
A private key representation for Aleo keypairs in JWK (JSON Web Key) format is defined, for local use only. Public key representation is via blockchainAccountId (CAIP-10) which uses an Aleo account address and network id (according to the proposed CAIP ChainAgnostic/CAIPs#84).

The functionality is enabled using a Cargo feature "aleosig". To run tests (with the feature enabled):

cargo test --features=aleosig aleo

This signature suite is intended to work with did:pkh:aleo (#348) as a verifiable credential issuer.
