The API wouldn't operate on streams. Instead, you pass a string, and
it either returns the detected encoding, or an information telling that
it needs more data. No streams.

The application would read data out of the stream, and pass it to
the detection. It then can process it in whatever manner it meant to
process it in the first place.
