Optimizations:
- Perhaps a lookup table can be used for quantization factors
-- Just malloc once in decode_intra_frame
- Determine what's more efficient: memset all coefficients to 0, or
just zero out the coefficients that need to be zero'ed out
- Use in place operations in IDWT, if that is possible
-- Make a special case for 1x1 codeblocks, perhaps merge the codeblock
- function into the subband function.
- Write IDWT in assembler
- Perhaps write arithmetic decoding in assembler
- Perhaps think about multithreading?
