New FLAC Decoder for HiFi Audio DSP Core

FLAC - the Free Lossless Audio Codec - is an audio format similar to MP3, but lossless so the audio is compressed without any loss in quality. Because it is not a proprietary format, is not encumbered by patents, and has an open-source reference implementation, FLAC has become increasingly popular. More information on FLAC is available at http://flac.sourceforge.net.
