/**
 * Instantiates an Account from a WebAuthn credential.
 *
 * @example
 *
 * ### Create Passkey + Instantiate Account
 *
 * Create a credential with `WebAuthnP256.createCredential` and then instantiate
 * a Viem Account with `Account.fromWebAuthnP256`.
 *
 * It is highly recommended to store the credential's public key in an external store
 * for future use (ie. for future calls to `WebAuthnP256.getCredential`).
 *
 * ```ts
 * import { Account, WebAuthnP256 } from 'tempo.ts/viem'
 * import { publicKeyStore } from './store'
 *
 * // 1. Create credential
 * const credential = await WebAuthnP256.createCredential({ name: 'Example' })
 *
 * // 2. Instantiate account
 * const account = Account.fromWebAuthnP256(credential)
 *
 * // 3. Store public key
 * await publicKeyStore.set(credential.id, credential.publicKey)
 *
 * ```
 *
 * @example
 *
 * ### Get Credential + Instantiate Account
 *
 * Gets a credential from `WebAuthnP256.getCredential` and then instantiates
 * an account with `Account.fromWebAuthnP256`.
 *
 * The `getPublicKey` function is required to fetch the public key paired with the credential
 * from an external store. The public key is required to derive the account's address.
 *
 * ```ts
 * import { Account, WebAuthnP256 } from 'tempo.ts/viem'
 * import { publicKeyStore } from './store'
 *
 * // 1. Get credential
 * const credential = await WebAuthnP256.getCredential({
 *   async getPublicKey(credential) {
 *     // 2. Get public key from external store.
 *     return await publicKeyStore.get(credential.id)
 *   }
 * })
 *
 * // 3. Instantiate account
 * const account = Account.fromWebAuthnP256(credential)
 * ```
 *
 * @param credential WebAuthnP256 credential.
 * @returns Account.
