Request_rerun() function

Hey @apol96,

So Streamlit launched an internal st.session_state in version 0.84, and I have a seeking suspicion that the old class SessionState workaround will no longer work when you upgrade the Streamlit version

I imagine that you will need to update your code to use the new st.session_state feature or to pin your version to 0.83.

Happy Streamlit-ing!
