/**
* Takes multiple source Promises, each of which could resolve to a Response, a
* ReadableStream, or a [BodyInit](https://fetch.spec.whatwg.org/#bodyinit),
* along with a
* [HeadersInit](https://fetch.spec.whatwg.org/#typedefdef-headersinit).
*
* Returns an object exposing a Response whose body consists of each individual
* stream's data returned in sequence, along with a Promise which signals when
* the stream is finished (useful for passing to a FetchEvent's waitUntil()).
*
* @param {Array<Promise<workbox-streams.StreamSource>>} sourcePromises
* @param {HeadersInit} [headersInit] If there's no `Content-Type` specified,
* `'text/html'` will be used by default.
* @return {Object<{done: Promise, response: Response}>}
