Fix audio output
...
Up until now, the decoder didn't output anything
in the data buffer. This fixes all the issues
related to sample format, removes leftover code
and actually outputs some audio to data buffer.
With this, the only sample we have can be played.
Seeking is still broken though.

Use quantizer value read from bitstream
...
Currently the code initializes quantizer even
before reading it from bitstream and uses that
to dequantize samples.
