Linter fixes

[keawade]

I cloned this to start looking into how to make my own templates and ran into some linter issues. I've fixed most of them.

• Added missing dependencies
• Updated .eslintrc.js to work around a deprecation
• Disabled no-console rule
• Added lint npm script
• Fixed linter errors

There is still a linter warning on L315 of src/init/index.js but I didn't know your opinions on that so I just left it alone.

L315 is an old declaration. Could you fix it to Buffer.from?
