Update Auxilary Sites

[xavierholt]

There are a few external websites that are referenced by the docs, but are using older versions without the latest bugfixes. I'll need to figure out how / get permissions to update these when possible - hopefully for the 2.2.0 release. The main one is:

• The NPM package!

But there are also a few auxilary/example/doc sites:

• https://doc.gdb.tools/smilesDrawer/
• https://smilesdrawer.rocks/ (which redirects to...)
• https://smilesdrawer.surge.sh/

It might also be worth dropping some of these and moving the official documentation to GitHub Pages (which is also set up?) to make sure that the reference material stays in sync with the latest code.

@daenuprobst - Could you help me get permission to deploy the NPM package?
