- Introduced support for H3C devices by adding a new configuration file `config.conf` containing interface and VLAN settings.
- Created an expected output JSON file `config.expected.json` to validate the parsing of H3C configurations.
- Updated the test model cases to include H3C for comprehensive testing of device parsing functionality.
- Introduced a new test file `test_models.py` to implement unit tests for various device models in the `device_registry`.
- Added parameterized tests to validate the parsing of device configurations against expected JSON outputs and to ensure required sections are present in the parsed models.
- Enhanced test coverage for multiple device types including Mikrotik, Keenetic, Qtech, Huawei, Eltex, and Quasar.
