Module encoder 

FLAC audio encoder.

Encodes interleaved i32 PCM samples into FLAC frames.

Encoding pipeline

1. Frame blocking (split PCM into block-size chunks).
2. Per-channel LPC analysis (autocorrelation + Levinson-Durbin).
3. Residual computation (signal − LPC prediction).
4. Rice coding (optimal Rice parameter per partition).
5. Frame serialisation (FLAC binary format with CRC-16).
