Decouples DecoderState from the Decoder and makes DecoderState inherit
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.
