Add CodeQL workflow

[jorgectf]

Hello from GitHub Security Lab!

Your repository is critical to the security of the Open Source Software (OSS) ecosystem and as part of our mission to make OSS safer, we are contributing a CodeQL configuration for code scanning to your repository. By enabling code scanning with CodeQL, you will be able to continuously analyze your code and surface potential vulnerabilities before they can even reach your codebase. In fact, you may have seen some alerts already appearing on this pull request!

We’ve tested the configuration manually before opening this pull request and adjusted it to the needs of your particular repository, but feel free to tweak it further! Check this page for detailed documentation.

#### How often will the code scanning analysis run? By default, code scanning will trigger a scan with the CodeQL engine on the following events: * On every pull request — to flag up potential security problems for you to investigate before merging a PR. * On every push to your default branch and other protected branches — this keeps the analysis results on your repository’s *Security* tab up to date. * Once a week at a fixed time — to make sure you benefit from the latest updated security analysis even when no code was committed or PRs were opened. #### What will this cost? Nothing! The CodeQL engine will run inside GitHub Actions, making use of your [unlimited free compute minutes for public repositories](https://docs.github.com/en/actions/learn-github-actions/usage-limits-billing-and-administration#about-billing-for-github-actions). #### What types of problems does CodeQL find? By default, code scanning runs the [`default` query suite](https://docs.github.com/en/code-security/code-scanning/automatically-scanning-your-code-for-vulnerabilities-and-errors/built-in-codeql-query-suites#default-query-suite). #### How do I upgrade my CodeQL engine? No need! New versions of the CodeQL analysis are constantly deployed on GitHub.com; your repository will automatically benefit from the most recently released version. #### The analysis doesn’t seem to be working If you get an error in GitHub Actions that indicates that CodeQL wasn’t able to analyze your code, please [follow the instructions here](https://docs.github.com/en/code-security/code-scanning/automatically-scanning-your-code-for-vulnerabilities-and-errors/troubleshooting-the-codeql-workflow) to debug the analysis. #### Which source code hosting platforms does code scanning support? GitHub code scanning is deeply integrated within GitHub itself. If you’d like to scan source code that is hosted elsewhere, we suggest that you create a mirror of that code on GitHub.

This pull request sets up GitHub code scanning for this repository. Once the scans have completed and the checks have passed, the analysis results for this pull request branch will appear on this overview. Once you merge this pull request, the 'Security' tab will show more code scanning analysis results (for example, for the default branch). Depending on your configuration and choice of analysis tool, future pull requests will be annotated with code scanning analysis results. For more information about GitHub code scanning, check out the documentation.
