What's Changed
* Improved unit test coverage: we now have 100% coverage
* Fixed some small bugs in catalog store handling, missing XML element names, handling of arrays both in XML parsing and in programmatic creation of G2.
* Implement changes in recent updates to NewsML-G2 schema - now implements NewsML-G2 up to schema version 2.34 (April 2024 version)
* Adds support for NewsMessage, events and planning items - we now cover the full NewsML-G2 schema.
* Adding G2 version number so we can understand which version is being supported.
* Updated documentation
* Importing everything into `__init__` so users don't have to know in which file each class is defined.
