Fix latest files fetching

[digizeph]

This pull request introduces version 1.1.0 of the as2org-rs crate, adding new features for dataset discovery, improving documentation and testing, updating dependencies, and fixing several bugs. The release enhances usability by providing methods to fetch available dataset files, improves code maintainability with new constants, and significantly expands both documentation and test coverage.

New Features and API Enhancements:

• Added As2org::get_all_files_with_dates() to list available dataset files and their dates.
• Added As2org::get_latest_file_url() to fetch the latest dataset file URL.
• Introduced a BASE_URL constant for the CAIDA dataset location, streamlining URL construction.

Documentation and Usability Improvements:

• Overhauled the README.md to provide clearer installation, usage, and API documentation, including new examples and explanations of error handling and offline usage.
• Enhanced rustdoc with comprehensive examples and usage patterns, marking them with no_run to avoid network calls during doc tests.
• Improved code documentation and inline comments throughout the codebase.

Testing and Maintenance:

• Significantly expanded the test suite with 15 unit tests covering initialization, ASN lookups, sibling checks, organization mapping, and internal consistency.
• Updated oneio dependency to version 0.19.2, enabling HTTPS support and updating features for better compatibility.
• Added chrono as a dependency for date handling.

Bug Fixes and Minor Corrections:

• Fixed a regex pattern in get_most_recent_data() to properly match dataset file dates.
• Refactored URL construction to consistently use the new BASE_URL constant.
• Corrected a typo in the CHANGELOG.md and clarified field descriptions.

Versioning:

• Bumped crate version to 1.1.0 in Cargo.toml to reflect new features and improvements.
