   Apply a function (that returns a Validated) in the valid case.

   Apply a function (that returns a Validated) in the valid case. Otherwise return the original Validated.

   This allows "chained" validation: the output of one validation can be fed into another validation function.

   This function is similar to flatMap on Either. It's not called flatMap, because by Cats convention, flatMap is a monadic bind that is consistent with ap. This method is not consistent with ap (or other Apply-based methods), because it has "fail-fast" behavior as opposed to accumulating validation failures.
