BREAKING CHANGE: Improved file handling causes the report to show the file DMARC RUA report path in the report ([10](https://github.com/MozaicWorks/DMARCReporting/issues/10)).
Added support for Python 3.12 ([20](https://github.com/MozaicWorks/DMARCReporting/issues/20)).
Improved the release process to read the version number from the Python module version ([14](https://github.com/MozaicWorks/DMARCReporting/issues/14)).
Added support for GZip files with trailing garbage ([18](https://github.com/MozaicWorks/DMARCReporting/issues/18)).
BREAKING CHANGE: Included the DMARC RUA Report date range in the report ([12](https://github.com/MozaicWorks/DMARCReporting/issues/12)).

Fixed the incorrect reporting due to XML tag ordering ([19](https://github.com/MozaicWorks/DMARCReporting/issues/19) reported by [yaiqsa](https://github.com/yaiqsa)). Instead of positional tag parsing we now rely on xpath to parse the DMARC RUA XML reports.

Introduced `argparse` for command line argument parsing ([15](https://github.com/MozaicWorks/DMARCReporting/pull/15) by [beda42](https://github.com/beda42)).
Introduced `black` for code formatting ([15](https://github.com/MozaicWorks/DMARCReporting/pull/15) by [beda42](https://github.com/beda42)).
