 * @example
 *
 * ```typescript
 * import { OrderSigningUtils, SupportedChainId, UnsignedOrder } from '@cowprotocol/cow-sdk'
 * import { Web3Provider } from '@ethersproject/providers'
 *
 * const account = 'YOUR_WALLET_ADDRESS'
 * const chainId = 100 // Gnosis chain
 * const provider = new Web3Provider(window.ethereum)
 * const signer = provider.getSigner()
 *
 * async function main() {
 *     const orderToSign: UnsignedOrder = { ... }
 *     const orderSigningResult = await OrderSigningUtils.signOrder(orderToSign, chainId, signer)
 *
 *     const orderId = await orderBookApi.sendOrder({ ...orderToSign, ...orderSigningResult })
 *
 *     const order = await orderBookApi.getOrder(orderId)
 *
 *     const trades = await orderBookApi.getTrades({ orderId })
 *
 *     const orderCancellationSigningResult = await OrderSigningUtils.signOrderCancellations([orderId], chainId, signer)
 *
 *     const cancellationResult = await orderBookApi.sendSignedOrderCancellations({...orderCancellationSigningResult, orderUids: [orderId] })
 *
 *     console.log('Results: ', { orderId, order, trades, orderCancellationSigningResult, cancellationResult })
 * }
