feat: Install Codeflash optimizer github action

[misrasaurabh1]

This PR installs the Codeflash github action which optimizes all the future non-async Python code. I tested that it runs correctly on this PR. Codeflash will be like having an expert python performance engineer optimize every PR.

An admin would have to generate the API Key from app.codeflash.ai and set it up in repository secrets under the KEY CODEFLASH_API_KEY.
