use npm init <initializer> to add scripts to package.json?

[ff6347]

This would mean to make this a monorepo or add another repo called @inpyjamas/create-scripts to handle this. Since workspaces will land in npm7 I actually don't want to switch pnpm, yarn or lerna.
So from the time being a separate repo should be okay and could be imported into a monorepo if npm7 turns out to handle that well.

see

• https://docs.npmjs.com/cli/init
• https://github.com/xojs/create-xo

maybe use
