* Optimal huffman decoding for AAC taken from:
* "SELECTING AN OPTIMAL HUFFMAN DECODER FOR AAC" by
* VLADIMIR Z. MESAROVIC , RAGHUNATH RAO, MIROSLAV V. DOKIC, and SACHIN DEO
* AES paper 5436
*
* 2 methods are used for huffman decoding:
* - binary search
* - 2-step table lookup
*
* The choice of the "optimal" method is based on the fact that if the
* memory size for the Two-step is exorbitantly high then the decision
* is Binary search for that codebook. However, for marginally more memory
* size, if Twostep outperforms even the best case of Binary then the
* decision is Two-step for that codebook.
*
* The following methods are used for the different tables.
* codebook "optimal" method
* HCB_1 2-Step
* HCB_2 2-Step
* HCB_3 Binary
* HCB_4 2-Step
* HCB_5 Binary
* HCB_6 2-Step
* HCB_7 Binary
* HCB_8 2-Step
* HCB_9 Binary

/* RVLC scalefactor decoding
*
* RVLC works like this:
* 1. Only symmetric huffman codewords are used
* 2. Total length of the scalefactor data is stored in the bitsream
* 3. Scalefactors are DPCM coded
* 4. Next to the starting value for DPCM the ending value is also stored
*
* With all this it is possible to read the scalefactor data from 2 sides.
* If there is a bit error in the scalefactor data it is possible to start
* decoding from the other end of the data, to find all but 1 scalefactor.
