Hi.

My previous patch introduced Huffman for quantized data, this patch allows
to use Huffman for bit allocation indexes (abits). This is a less
significant improvement but still noticeable in case of limited bitrate. In
case of DIN_45403 input sample I got:
before:
Best PSNR is  44.47 for shift 0
after:
Best PSNR is  46.64 for shift 0

Thank you.
