    A class for executing tasks that have a primary executor and a fallback mechanism.
    
    Attributes:
        primary_exec (callable): The main function to execute the task.
        fallback_exec (callable): The backup function used when the primary fails.
        exception_types (tuple of BaseException): Exception types to catch during execution.

    Methods:
        execute(task_data: dict) -> Any:
            Executes the primary executor with provided data. Falls back to the
            secondary executor if an error occurs as specified by `exception_types`.
