Rule proposal: Enforce empty line below imports

[sindresorhus]

I'm aware this is purely stylistic, but thought I'd propose it since it seems this plugin will soon expand to stylistic rules with the adoption of https://github.com/jfmengels/eslint-plugin-import-order

Fail

import foo from 'foo';
import bar from 'bar';
const unicorn = true;

const foo = require('foo');
const bar = require('bar');
const unicorn = true;

Pass

import foo from 'foo';
import bar from 'bar';

const unicorn = true;

const foo = require('foo');
const bar = require('bar');

const unicorn = true;

Sounds good to me, will accept a PR.

Oh weird, expected #245 to close this but I guess it didn't mention it explicitly.
