CompressionUtils

Utility class for HTTP request/response body compression and decompression.

This class provides static methods for compressing and decompressing data using the compression algorithms defined in CompressionEncoding.

Supported compression formats:

• GZIP - Always available (built into Java). The de facto standard for HTTP compression.

• Brotli - Requires optional dependency: com.aayushatharva.brotli4j:brotli4j. Provides 20-26% better compression than GZIP.

• Zstd - Requires optional dependency: com.github.luben:zstd-jni. Very fast compression/decompression with excellent ratios.

Usage example:

`// Check if an encoding is available
if (CompressionUtils.isEncodingAvailable(CompressionEncoding.BROTLI)) {
byte[] compressed = CompressionUtils.compress(jsonBody, CompressionEncoding.BROTLI);
}

// Compress request body (falls back to GZIP if preferred encoding unavailable)
String jsonBody = "{\"messages\": [...]}";
byte[] compressed = CompressionUtils.compress(jsonBody, CompressionEncoding.GZIP);

// Decompress response body
byte[] compressedResponse = ...;
String decompressed = CompressionUtils.decompressToString(compressedResponse, CompressionEncoding.GZIP);
