groupBy resultSelector values type is incorrect

[patsissons]

IxJS version: 2.3.1

Additional information:

createGrouping returns the grouped items as an array instead of an Iterable.

@patsissons but an Array is an Iterable, unless you're thinking it must be an IterableX type.

I don't see Iterable being assignable to Array (or vice versa), I am now on 2.3.4. The issue I am encountering is that the groupBy resultSelector values param is typed as Iterable, but I cannot use any Iterable operators on it because it is actually just an Array.
