Crate apfsds_obfuscation 

APFSDS Obfuscation - Traffic obfuscation utilities

This crate provides:

• SIMD XOR mask (AVX2 + portable fallback)
• Smart padding (matching target distribution)
• Compression utilities
• Timing jitter
• Decoy traffic generation

Calculate delay based on packet timing to avoid detection

compress

Compress data using zstd

compress_if_needed

Compress data using zstd if above threshold

compress_with_level

Compress data with specific level (1-22)

decompress
