d1ea26f640 Do not try to read residue if ave_mean <= 1
Otherwise, we end up with with log(0) or log(1). av_ceil_log2 simply
assumes the argument is non-zero and returns wrong result when it is.
(Not that there is a proper way of returning an undefined value.)

2083a10abf 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.

3d84495128 Use quantizer value read from bitstream
Currently the code initializes quantizer even
before reading it from bitstream and uses that
to dequantize samples.
