     * The ExportOnly mode for HPKE AEAD implementing {@link AeadInterface}.

     * When using `@hpke/core`, the instance of this class must be specified
     * to the `aead` parameter of {@link CipherSuiteParams} instead of `AeadId.ExportOnly`
     * as follows:
     *
     * @example
     *
     * ```ts
     * import {
     *   CipherSuite,
     *   DhkemP256HkdfSha256,
     *   ExportOnly,
     *   HkdfSha256,
     * } from "@hpke/core";
     *
     * const suite = new CipherSuite({
     *   kem: new DhkemP256HkdfSha256(),
     *   kdf: new HkdfSha256(),
     *   aead: new ExportOnly(),
     * });
