James Munns: thanks for your awesome RustNL talk (well, again 🙂) Couple questions on `postcard-rpc`:
- out of curiosity, did you consider using an `impl futures::stream::Stream` instead of `Subscription`? Or maybe even `TryStream`, since there are errors that might be material/useful to surface to the crate user (e.g. device disconnected vs deserialisation failure)
- do you think there are cases when USB-CDC is better than raw bulk transfers?

Also, TIL that the "less-than-full-packet" framing is a part of the USB spec and not a convention, shame on me for missing it lol (and doing COBS over bulk transfers)
