baicai-1145 17cb2e5acf Implement G2PW processing enhancements in TTS framework
Add support for G2PW processing in the TTS system by introducing new methods and classes for handling G2PW segments. Update PrepareCoordinator to manage G2PW worker threads and integrate G2PW profiling into the existing framework. Enhance text preprocessing to identify segments requiring G2PW and streamline the resolution of these segments. This update improves the overall performance and maintainability of the TTS system by optimizing the handling of Chinese text processing.
