v3.3.0

What's Changed

❗ Almost x2 speed for CAR decoding (Bluesky firehose), ~25-35% faster DAG-CBOR decoding, and ~17% faster CID decoding!

I do have more ideas on what to try to speed it up even further! For example, applying BOLT on top of the existing PGO.

⚡ Optimizations

• Huge performance gain for DAG-CBOR decoding and CID by replacing deprecated Rust crate libipld with cbor4ii by @vmx in #80 and even contributed upstream!
• Optimize DAG-CBOR encoding for arrays and maps by @MarshalX in #88
• Optimize CAR decoding by reducing allocations by @MarshalX in #90
• Optimize executable size (panic = "abort") by @MarshalX in #86

Other

• Add pytest-benchmark GitHub Actions workflow by @MarshalX in #82
• Add lint and format check GHA workflow by @MarshalX in #83
• Add CONTRIBUTING.md by @MarshalX in #85
• Update CodSpeed by @MarshalX in #81
• Fix formatting in profiling by @MarshalX in #84
