from Module so that Decoder can function independent of DecoderSTate and DecoderState can more cleanly interface with other modules. Resolves issue with LTR-type decoders where the AudioModule was filtering demodulated audio buffers before the decoder received the audio - demodulated audio buffers are now copied before creating AudioPackets.
