Allow more lines for 'no-multiple-empty-lines'

[martpie]

One line spacing is not enough. It does not let us distinct global code areas

import tada from 'tada';
import moment from 'moment';


export const App = () => {
  console.log(1);
  console.log(2);

  doSth();
}

2 lines between big things (import, main declaration, export...), 1 line between methods internal is imho the way to go.

Real world example: separating tests from previous declarations.

I can see some advantages with this approach, but there is no way of creating a rule for this.
Therefore, could lead to inconsistency depending what one thinks is the best way of separating the code.

But if we don't want to be too oppionated and avoid this error, IMO we should not allow more than 2 lines though.

My point is not to enforce my way of doing things, we'll never agree :p, just to move the limit from one to two lines 😄
