feat: Enhance DALI Gateway with RGBW and RGBCW support

- Added support for RGBW and RGBCW color modes in the DALI Gateway.
- Updated JSON color mode parsing to handle new color types.
- Extended the StoreDt8SceneSnapshot function to include white, amber, and free color parameters.
- Introduced new methods in DaliGatewayBridge for setting RGBW, RGBCW, and RGBWAF colors.
- Modified KnxDaliChannel to send RGBW and RGBCW colors based on the color type.
- Updated parameter types and definitions in the KNX product XML files to accommodate new color modes.
- Enhanced README with migration details and validation instructions.
