v0.2.7

• added specific_model parameter which allows using XTTS model checkpoints like "2.0.2" or "2.0.1"
  • currently set to "2.0.2" as a default because 2.0.3 seems to perform worse
  • set to None if you want to always use the latest model
• added local_models_path
  • if not specified specific_model models will be loaded in a directory "models" in the script directory
  • if no specific_model is set it will use coqui's default model directory (users/start/appdata/local/tts under Windows)
• added use_deepspeed parameter in case anybody has it installed
• added prepare_text_for_synthesis_callback parameter in case the default handler for preparing text for synthesis fails (maybe due to using a language I am not familiar with) and you want to implement your own
