🐛 [BUG] - Markdownlit

Description

In Markdownlit it uses "st.experimental_memo" which should be changed to "st.cache_data". Using st.experimental_memo I've found that my app crashes on importing markdownlit (from markdownlit import mdlit) with the error "streamlit.errors.StreamlitAPIException: set_page_config() can only be called once per app"

Reproduction steps

1. pip install markdownlit
2. from markdownlit import mdlit
3. produce error; streamlit.errors.StreamlitAPIException: `set_page_config()` can only be called once per app, and must be called as the first Streamlit command in your script.
