Streamlit: Open in wide mode

[RNogales94]

Problem

First thing my users do when start the streamlit application is switch on the wide mode.
Could I directly open streamlit in wide mode?

Solution

A simple solution could be add a parameter when launch the streamlit
MVP:
streamlit run --wide <app.py>

Preferred solution:
Customize streamlit at the beginning of the application something like
st.set_wide_mode()

Probably I could do the enhancement but I'm not familiar with the structure of the project

Seems this is already there. Refer #314
