Add interfaces and vlans methods to Qtech model; update TTP template

- Implemented the `interfaces` method to process IP addresses and netmasks, adding a calculated mask to the output.
- Added the `vlans` method to handle VLAN data, supporting both individual and grouped VLAN IDs.
- Updated the QTECH TTP template to include a new version field and improved formatting for VLAN definitions.
