Similar to IStringStream but using an externally managed buffer for its input. This allows the input buffer to be filled (and refilled) from various sources.
Note that this stream will normally be used as a "one-shot" reader. Caution must be exercised that the referenced buffer remains valid and without any intermediate resizing for the duration of the stream's use.
