/**
* A buffered region file implementation that provides efficient chunk storage and retrieval
* with compression, checksums, and automatic compaction capabilities.
*
* <p>This implementation includes:
* <ul>
* <li>Zstandard compression for chunk data</li>
* <li>XXHash32 checksums for data integrity verification</li>
* <li>Automatic file compaction when fragmentation exceeds thresholds</li>
* <li>Thread-safe operations with read-write locks</li>
* <li>Direct ByteBuffer usage for memory efficiency</li>
* </ul>
*
* <p>For conversion tools between MCA and buffered region file formats, see:
* <a href="https://github.com/NONPLAYT/LinearRegionFileFormatTools">LinearRegionFileFormatTools</a>
