//! # Common Ogg Container Parsing
//!
//! This module provides shared functionality for parsing Ogg containers,
//! used by both Ogg/Vorbis and Ogg/Opus decoders.
//!
//! ## Features
//!
//! - **Streaming packet assembly**: Reads Ogg pages and assembles multi-page packets
//! - **Optional CRC32 validation**: Can validate page integrity
//! - **Optional sync search**: Can search for "OggS" pattern in streams with garbage
//! - **Shared error type**: Uses `OggContainerError` for consistent error reporting
//!
//! ## Architecture
//!
//! The `OggPacketReader` reads Ogg pages incrementally:
//! 1. Optionally searches for "OggS" sync pattern
//! 2. Reads 27-byte page headers
//! 3. Optionally validates CRC32 checksums
//! 4. Reads segment tables and page data
//! 5. Assembles packets from segments (handling multi-page packets)
//! 6. Returns complete packets to the decoder
