bump node to current LTS & adapt build accordingly

This fix #127

The main blocker was streamlit-component-lib not upgrading to v2

I think it's probably best to actually pin the package requirements as well until we figure out a solution to the folium 0.15 bug

Not sure hat you mean here : I set folium>=0.13,<0.15 for both requirement.txt files already. You mean you want folium==0.14 exactly ?

Sorry, it's a bit confusing -- there are 3 different sets of requirements in this repo:

1. requirements.txt -- for the demo app
2. test/requirements.txt -- for the tests
3. setup.py -- for the package

You should actually just be able to change the requirements in the package, and have it work, since the requirements.txt files should also install the package dependencies

done !

Thanks!
