feat(rules): prefer-hooks-on-top

[Mark1626]

Fixes #356

Approach is to maintain a stack of boolean which gets marked as true when a hook is not before a test

Also an edge case

describe("foo" () => {
  beforeEach(() => {
    //some hook code
  });
  
  // Not affected by rule
  someSetup();

  afterEach(() => {
    //some hook code
  });
  test("bar" () => {
    some_fn();
  });
});
