Kata already present in codewars

There could be more test cases so we can verify our progress while we work on this kata.

This kata is a duplicate and either needs to introduce a defining factor or be unpublished.

That's not the way to write tests.

Try Test.assertEquals(romanize(42), "XLII");

Then, for the random tests, define your own _romanize function in the tests box and Test.assertEquals(romanize(n), _romanize(n));

Also, take romanize out of Preloaded. That's not what it's for.
