Update to create-react-app 3.4.1

While trying to figure out why the ansi patch wouldn't
build it emerged that we're now 2 major releases behind
on create-react-app.

Update create-react-app to the latest 3.4.1. This also updates
react to 16.13, and updates eslint globals processing so that
we don't have to declare globals in headers when we've
declared them already in the eslint file.

Finally, although this doesn't do it, create-react-app 3
has support for typescript, so if we want we can start migrating
files to .ts or .tsx extensions and start doing typing in
them.

Pin nanoid to v2 until such a time as create-react-app can be
updated to 3.4.2 which is needed ot handle .cjs extensions
being used by nanoid.
