Patch v1.3.0

[ifilot]

Changes

• Add D2O compression support for zstd and blosc, including protocol IDs, decompression support, round-trip verification, and auto-selection benchmarking.
• Modernize the CMake setup with target-based dependencies, generated config files in the build tree, proper install targets, imported pkg-config dependencies, and updated project versioning.
• Update GitHub Actions to use modern CMake/CTest commands, newer checkout/codecov actions, clearer dependency installation, and shared-library verification.
• Add a reusable CLI formatting helper for banners, key/value output, compression benchmark tables, elapsed-time summaries, and terminal-aware progress bars.
• Replace fragile MD5-based mesh-output tests with structural validation for .obj, .ply, and .stl files.
• Expand compression tests to cover gzip, lzma, bzip2, zstd, blosc, and auto-compression.
• Keep TestGenerator active in coverage builds, improving coverage honesty for generated datasets.
• Update README, docs, examples, and Docker setup for the new dependencies and supported formats.
