Systematically benchmark compression algorithm, compression factor, block size #44

Execute a systematic and reproducible benchmark to find the optimal combination of

• Compression algorithm
• Compression factor
• Block size

in terms of

• File size
• Applicartion startup time
• zsync efficiency (delta update size)

for

• zlib
• lzma
• zstandard
• dwarfs
• libdeflate
