Add `chainTransformers` and `map` utilities (dart-lang/stream_transform#47)

These are a bit different than others in this package since we would
generally not expect to see them directly inlined to a call to
`transform`, but are instead useful when dealing with variable or
arguments of type `StreamTransformer`, for instance `StreamSinkTransformer.fromStreamTransformer`.
