Introduce a new feature that allows users to choose between a "lite" and a "full"

cost of speed. This selection can be made through the CLI or API, providing
flexibility for different use cases.

update:Add md make mode config in do_parse.You can control whether the produced md is for NLP or MM by changing the value of f_make_md_mode
