ADPCM-XQ Version 0.5 Release

Major update to ADPCM-XQ with many new features and performance gains:

• Added non-standard 2-bit, 3-bit, and 5-bit IMA ADPCM options
• Greatly improved encoding speed for high depth lookahead
• Increased command-line maximum search depth from 8 to 16
• Added option (-x) for old "exhaustive" searches (very slow)
• Added option (-n) to calculate encode quantization noise
• New improved dynamic noise shaping (DNS) algorithm from WavPack
• New option (-s) to enable fixed noise shaping and set slope
• Essentially backward-compatible library API

Windows and Mac binaries attached. Thanks to @gingerbeardman for the Mac build!
