/**
 * Returns the permit struct consumed by VaultExitBundlesV1 from an optional vault-share
 * requirement signature.
 *
 * Without a signature, returns the contract's empty-permit sentinel. With a signature, validates
 * the ERC-2612 kind and vault asset before splitting the serialized signature.
 * Owner, spender, deadline, nonce, and cryptographic validity are verified onchain by the vault.
 *
 * @param params.vault - Vault share token authorized by the permit.
 * @param params.deadline - Bundle deadline used by the empty-permit sentinel.
 * @param params.requirementSignature - Optional signed bounded ERC-2612 requirement.
 * @returns The VaultExitBundlesV1 permit tuple.
 * @throws {VaultExitBundlesV1PermitMismatchError} when the requirement has the wrong permit kind, asset, or signature encoding.
 * @example
 * ```ts
 * import { getVaultExitBundlesV1PermitStruct } from "@morpho-org/morpho-sdk";
 *
 * const permit = getVaultExitBundlesV1PermitStruct({
 *   vault,
 *   deadline,
 *   requirementSignature,
 * });
 * // permit satisfies VaultExitBundlesV1PermitStruct
 * ```
