Wide PDFs, Antialiasing, Minor Improvements

[patinthehat]

This PR introduces several enhancements and fixes across the codebase, focusing on improving PDF handling, updating workflows, and adding new test utilities. Key changes include updates to support ultra-wide PDFs, enhancements to the CI workflow, and new helper functions for testing.

It resolves #245, which adds antialias support when saving images, and #248, which is a bug report indicating ultra-wide PDFs cannot be loaded. The docs have been updated to reflect the changes necessary in the Imagick policy config file to allow loading these files.

Enhancements to PDF Handling:

• Added support for ultra-wide PDFs by introducing changes to the Imagick policy configuration and documenting the process in the README.md. [1] [2]
• Updated the Pdf class to initialize Imagick as nullable and replaced null checks with empty() for better readability and flexibility. [1] [2] [3]

Continuous Integration Workflow Improvements:

• Updated the PHP matrix in .github/workflows/run-tests.yml to include PHP 8.4.
• policy.xml file on the test runner is updated to allow for ultra-wide PDFs.
• Enabled parallel execution for tests in the CI pipeline to improve performance.

Testing Enhancements:

• Added utility functions (get_test_file, test_file, and output_file) in tests/Pest.php to streamline test file handling.
• Introduced a new WidthTest.php file to validate support for ultra-wide and wide PDFs, ensuring proper functionality and output.

Other

• Minor grammatical changes to docs & comments.
