fix(resample): function name changed in dependent package (#22)

in v0.9.8 the Resample Package was refactored, this resulted in the `setStream` being renamed `setOutput`. This took a good while to track down because it wasn't clear why the `override` was throwing an error on the `virtual` `void`.

This brings the code back into a functional state.
