This commit adds a decoder for the frequency-domain part of USAC. What works: - Mono - Stereo (no prediction) - Stereo (mid/side coding) - Stereo (complex prediction) What's left: - SBR - Speech coding Known issues: - Desync with certain sequences - Preroll crossover missing (shouldn't matter, bitrate adaptation only)
