/**
 * The Request ID middleware generates a unique ID for each request and stores it in the Router context, this can be useful to log the request and response information and correlate them.
 *
 * ```ts
 * import { createRequestIDMiddleware } from "remix-utils/middleware/request-id";
 *
 * export const [requestIDMiddleware, getRequestID] =
 *   createRequestIDMiddleware();
 * ```
 *
 * To use it, you need to add it to the `middleware` array in your `app/root.tsx` file.
 *
 * ```ts
 * import { requestIDMiddleware } from "~/middleware/request-id.server";
 *
 * export const middleware: Route.MiddlewareFunction[] = [requestIDMiddleware];
 * ```
 *
 * And you can use the `getRequestID` function in your loaders, actions, and other middleware to get the request ID.
 *
 * ```ts
 * import { getRequestID } from "~/middleware/request-id.server";
 *
 * export async function loader({ request }: Route.LoaderArgs) {
 *   let requestID = getRequestID();
 *   // ...
 * }
 * ```
 *
 * By default the request ID is a UUID, but you can customize it by passing a function to the `createRequestIDMiddleware` function.
 *
 * ```ts
 * import { createRequestIDMiddleware } from "remix-utils/middleware/request-id";
 *
 * export const [requestIDMiddleware, getRequestID] =
 *   createRequestIDMiddleware({
 *     generator() {
 *       return Math.random().toString(36).slice(2);
 *     },
 *   });
 * ```
 *
 * The middleware also gets the request ID from the `X-Request-ID` header if it's present, this can be useful to correlate requests between services.
 *
 * If you want to use a different header you can pass the header name to the `createRequestIDMiddleware` function.
 *
 * ```ts
 * import { createRequestIDMiddleware } from "remix-utils/middleware/request-id";
 *
 * export const [requestIDMiddleware, getRequestID] =
 *   createRequestIDMiddleware({
 *     header: "X-Correlation-ID",
 *   });
 * ```
