feat(patch): Export results in json format readable by github-action-benchmark

[vsarunas]

Description

Export results that can be read by https://github.com/benchmark-action/github-action-benchmark

Create the baseline and then export it to json format, for example metrics except for the throughput are here; this will create a file main.json:

benchmark baseline read main --format jsonSmallerIsBetter

Which can be passed to the github-action-benchmark action:

      - name: Store benchmark result
        uses: benchmark-action/github-action-benchmark@v1
        with:
          name: 'Benchmarks'
          tool: 'customSmallerIsBetter'
          output-file-path: main.json

Minimal checklist:

• I have performed a self-review of my own code
• I have added DocC code-level documentation for any public interfaces exported by the package
• I have added unit and/or integration tests that prove my fix is effective or that my feature works
