Custom Home Assistant component for Roth Touchline

This component overrides the bundled touchline component in Home Assistant.

Why this is better than the bundled integration

• Modern Configuration: Supports Home Assistant's UI-based configuration (Config Flow), eliminating the need to edit configuration.yaml manually.
• Asynchronous Execution: Built using asyncio, ensuring that it doesn't block the Home Assistant main thread during network operations, leading to better overall performance and stability.
• Enhanced Library: Uses pytouchline_extended, providing improved communication with Roth Touchline devices.
• Seamless Override: Automatically takes precedence over the built-in integration while maintaining the same touchline domain.
