"say" exercise doesn't use "and" in hundreds

[Grazfather]

We explicitly have a test:

(deftest one-hundred-twenty-three-test
  (is (= "one hundred twenty-three" (say/number 123))))

But in the description:

• 14 becomes "fourteen".
• 100 becomes "one hundred".
• 120 becomes "one hundred and twenty".
• 1002 becomes "one thousand and two".
• 1323 becomes "one thousand three hundred and twenty-three".

Seems are tests are much simpler (the examples conditionally add and between thousands or hundreds, depending on the value).

Indeed, a look at the problem specs shows that the test is correct, so the description should be changed accordingly.

EDIT: Wait... now I think I get it. The section in question ("Extensions") is only meant to be a suggested optional exercise (extension) for the student, not a description of the exercise itself. Still, I find that to be confusing and in the PR I just removed that part.
