Refactor and update

[alphaolomi]

Summary

This pull request introduces several enhancements and new features to the alphaolomi/mrz PHP library. It notably includes the addition of GitHub funding information, an extensive testing setup via GitHub Actions for PHP versions 8.1 and 8.2 across various platforms, and a revision of the .gitignore file to align with best practices. The changes aim to streamline the development process, enhance code quality, and improve community engagement.

Changes

1. GitHub Funding: A new FUNDING.yml file has been added to the .github directory, enabling the GitHub Sponsors button for the repository. This change opens up opportunities for community sponsorship, supporting the ongoing development and maintenance of the project.

2. Testing Setup: The project now includes a comprehensive testing setup, implemented via GitHub Actions. The workflow, defined in run-phpunit-tests.yml, executes tests across a matrix of operating systems (Ubuntu and Windows) and PHP versions (8.1, 8.2), ensuring compatibility and robustness across different environments.

3. .gitignore Revision: The .gitignore file has been updated to exclude additional files and directories such as .php_cs, .phpunit.result.cache, and composer.lock, among others. This update prevents unnecessary files from being tracked by Git, keeping the repository clean and focused on source code.

4. Miscellaneous: Minor adjustments and improvements have been made to the documentation and codebase to enhance clarity and maintainability.

Impact

These changes are expected to positively impact the project by:

• Enhancing Community Engagement: Through the GitHub Sponsors program.
• Improving Code Quality and Reliability: By establishing a robust testing framework.
• Maintaining a Clean Repository: By revising the .gitignore file.

Next Steps

• Community Feedback: Encourage community feedback and contributions to further refine and enhance the library.
• Continuous Integration: Monitor and optimize the GitHub Actions workflows for efficiency and coverage.
