Added support for high throughput (HTJ2K) decoding.

There are a few limitations:
- mixed mode (HT and regular code blocks) is not supported.
- ROI in HT blocks is not supported.
- Placeholder passes are not supported.
- MultiHT sets are not support, only a singleHT set.
- there are known issues with some compliance testing files related to
  the parsing of packet header.
