Streamlit-folium

This release adds bi-directional support via the `st_folium` function. When calling `mapdata = st_folium(m)`, a dict will be returned back to Python with the bounding box and other click data. Improved documentation will come in a future release as time allows, but you can see the `examples` folder for ideas of how to use this new functionality.
