[Python] Coerce value_set argument to array in "is_in" kernel

[asfimport]

Small example I ran into:

>>> arr = pa.array(['a', 'b', 'c', 'd'])
>>> pc.is_in(arr, ['a', 'c'])
...
TypeError: "['a', 'c']" is not a valid value set

That's not a super friendly error message (it was not directly clear what is not "valid" about this). Passing pa.array(['a', 'c']) explicitly works, but I expected that the kernel would try this automatically (as we also convert the first array argument to an array).
