Add multi-phase support for VZLogger powermeter

[tomquist]

Summary

Added support for multi-phase power meters in the VZLogger integration by allowing comma-separated UUID values to be configured. Each phase is now fetched in parallel for improved performance.

Key Changes

• Modified VZLogger.__init__() to accept either a single UUID string or a list of UUIDs, normalizing both to an internal list
• Updated get_json() to accept a UUID parameter, enabling per-UUID queries
• Refactored get_powermeter_watts() to fetch all phase UUIDs in parallel using asyncio.gather() and return a list of power values (one per phase)
• Added asyncio import to support concurrent phase fetching
• Updated configuration loader to parse comma-separated UUID values using the existing _split_labels() utility
• Added comprehensive test case test_vzlogger_three_phase() validating multi-phase functionality and parallel requests
• Updated documentation (README.md and config.ini.example) with examples of 3-phase meter configuration
• Added changelog entry documenting the new feature

Implementation Details

• Backward compatible: single UUID strings are automatically converted to a single-element list
• Phases are fetched concurrently rather than sequentially, improving response time for multi-phase meters
• Configuration uses comma-separated values consistent with other multi-phase powermeters in the codebase (Tasmota, MQTT)
