/**
 * Encodes `Midnight.setConsumed` to cancel or partially consume an offer group.
 *
 * App flows should usually call `client.morpho.midnight(chainId).cancelOffer(...)`.
 * Use this builder directly when the group id is already known and no
 * additional requirements are needed. Omitting `amount` fully cancels the group
 * by setting consumption to {@link MAX_OFFER_CAP}.
 *
 * @param params.chainId - Chain id used to resolve `Midnight`.
 * @param params.group - Offer group id to mark consumed.
 * @param params.onBehalf - Maker whose group consumption is updated.
 * @param params.amount - Optional consumed amount; defaults to {@link MAX_OFFER_CAP} for full cancellation.
 * @param params.metadata - Optional analytics metadata appended to calldata.
 * @returns A deep-frozen `Transaction<MidnightCancelOfferAction>` targeting `Midnight`.
 * @throws {NegativeInputError} when `amount` is negative.
 * @throws {MidnightAmountExceedsMaxOfferCapError} when `amount` exceeds {@link MAX_OFFER_CAP}.
 * @example
 * ```ts
 * import { midnightCancelOffer } from "@morpho-org/morpho-sdk";
 *
 * const tx = midnightCancelOffer({
 *   chainId: 8453,
 *   group,
 *   onBehalf: maker,
 * });
 * ```
