What's changed

• This release adds CodeCov to Ozon3, providing test coverage analysis for the repo, and ensuring that the reliability of the codebase is prioritized.
• This includes a CodeCov CI/CD file to upload an analysis report to CodeCov after every push to 'main'
• Also includes a badge in the README to allow for easy viewing of the test coverage percentage. That should give new users some more confidence to use Ozon3!
