/**
 * Generates an Ed25519 key pair from the provided mnemonic.

 * The mnemonic is converted into a seed through the use of argon2id.
 * The password is used as a salt for argon2id.
 * From the generated seed we extract the key pair.
 *
 * @param mnemonic - Sequence of words from the predefined wordlist
 * @param password - Optional salt for the seed derivation
 * @returns An Ed25519 key pair
