ci: introduce benchmarks for CI

[techraed]

This PR introduces:

• CI job which runs benchmarks in case run-benchmarks label is set in a PR and specific paths were changed (rs/, benchmarks/, examples/, Cargo.*, and the job config). Also in case the PR is pushed to master, the bench will run.
• bench-analyzer scripts which reads 2 files with bench data and prints a table with bench statistics. Optionally returned table can be set to the file. Also in case threshold is introduced, if any bench doesn't pass threshold (i.e. current bench differs from the other by threshold value) the script ends with an error

Pull Request Overview

This PR introduces a CI workflow for running benchmarks on Rust code changes. The workflow compares benchmark results between the PR branch and the master branch to detect performance regressions.

• Adds a GitHub Actions workflow that triggers on labeled PRs and pushes to master
• Introduces a new binary utility for converting benchmark data formats
• Configures the workflow to compare performance and comment on PRs with results
