No ordered iterable type is exported

[patsissons]

IxJS version: 2.0.1

Code to reproduce: let source: OrderedIterable<number> = Iterable.from([1]).orderBy(x => x)

Expected behavior: No type definition errors on OrderedIterable

Actual behavior: no exported member OrderedIterable<T>

Additional information:

This is useful if we ever need to define an unassigned ordered iterable variable. It's also convenient if we want to re-assign a variable via dynamic chaining (i.e. orderby, if condition thenby).

This ought to be a relatively simple fix. The simple version is to simply export OrderedIterableBaseX as OrderedIterable in the api surface. A slightly more involved fix is to create an actual OrderedIterable interface and export that (though i doubt it provides any benefits over the simple fix).

I'm not sure how strictly important this is as the work-around is relatively simple and the people that may actually make use of this is possibly quite small.

@patsissons can you verify now?

I believe that is nearly identical to what I had stubbed in during testing.
