IMA ADPCM Stereo wav length half reduced #56

Hi.

I'm using libnyquist. And found that while decoding wavs of type IMA ADPCM of two channels the length of the decoded file is reduced to half. If I add

        if (wavHeader.channel_count == 2)
          totalSamples *= 2;

On WavDecoder.cpp line 309 the problem seems to be fixed.

But I'm not sure if it is the right solution.

Thanks.
