Stream ID not available?

From [web-transport-quinn/README.md](https://github.com/kixelated/web-transport-rs/blob/ecddd9442e921f10db4a3188d653980c0f087574/web-transport-quinn/README.md): > When possible, Deref is used to expose the underlying Quinn API. However some of the API is wrapped or unavailable due to WebTransport limitations. > * Stream IDs are not avaialble. However, both [WebTransport over HTTP/3](https://datatracker.ietf.org/doc/html/draft-ietf-webtrans-http3#section-5.3) and the [W3C WebTransport spec](https://www.w3.org/TR/webtransport/#dom-webtransport-createbidirectionalstream) refer to a (session-level) stream ID. And if I'm not misunderstanding `quinn` code, their `SendStream` and `RecvStream` indeed have a stream ID that we can just expose?
