feat: add support for 2.5 pro advanced model

feat: add support for file input

important: from v1.10.0, `images` parameter in `GeminiClient.generate_content` and `ChatSession.send_message` is deprecated, current users may need to modify their codes to use `files` instead. Also note that `files` doesn't support bytes input, only path string or `pathlib.Path` object are supported.
