Documentation: Clarify that capture_http writer with filename has no get_stream methood

[wumpus]

This is by design. I agree that this isn't obvious and that we can improve the documentation and runtime error messages for this case.

What you should do instead is do the capture to a file, and once that's done, read that file.

Thanks @wumpus, should I leave this open as a documentation bug in that case?

[wumpus]

Yes, please leave it open, this is not the only place where we have a lack of clarity about streaming vs files.
