Issue with functions that take varargs about resumablefunctions.jl

[BenLauwens]

Hi

I tested your interleave example and it seems fine. So I will release a new version of ResumableFunctions, so that you can update your blog;)

I wanted to include this as an example in:
http://white.ucc.asn.au/2017/11/18/Lazy-Sequences-in-Julia.html

I can still go back an add it later of-course.

Ah, I have it.

ResumableFunctions doesn't handle functions with varargs right.

@resumable function foo(xs...)
    @yield xs[1]
    @yield xs[2]
end

collect(foo(3,4))

Output:

BoundsError: attempt to access ((3, 4),)
  at index [2]

Stacktrace:

Hi

The problem is the splatting of the varargs. I have implemented a fix in the master branch. I added a test and it seems to work... Can you test that this solves your problem.
Thanks!

Done and looking good
