 * the KDF keeps as mutable state. A KDF instance shared by multiple cipher
 * suites (e.g. the same `HkdfSha256` paired with different AEADs) would
 * therefore end up with the `suite_id` of the suite created last.
 *
 * The returned object inherits everything from `kdf` through its prototype
 * chain, while state assigned afterwards (such as the `suite_id`) is stored
 * on the returned object itself. The given instance is never modified.
