This file contains the implementation of a DSF decoder that converts Direct Stream Digital (DSD) audio data to Pulse Code Modulation (PCM) format. The decoder supports the DSF file format which is commonly used for high-resolution audio distribution.

Key features:

• DSF file header parsing and validation
• DSD bitstream to PCM conversion with configurable decimation
• BiQuad low-pass filtering for anti-aliasing
• Streaming-compatible operation for real-time processing
• Support for stereo DSD files (DSD64 and higher sample rates)
