There were couple of bugs in the ADX decoding code:
- Fix bug where any looping ADX would not decode and error, and invalid ADX wouldn't.
- Fix bug on writing PCM data on ADX decoding.
- Fix bug on writing looping information for the resulting decoding.
- Fix bug where on an edge case, last frame of the ADX would not be decoded.
- Fix bug where a 'segfault' may occur on decoding.
- General memory management improvement and patching memory leaks.
