Type guessing dates causes performance issues about messytables HOT 3 CLOSED

One proposed fix would be to make a single regex out of the various date formats instead of using N of them, but I don't know whether python's re is powerful enough to signal more than one end state.

We don't seem to be using regexes for this. From what I can tell, we're
doing datetime.strptime repeatedly with multiple formats until one of
them doesn't throw an exception. That sounds less than ideal :)

I'd recommend using the DateUtilType that you can find here: https://github.com/okfn/messytables/blob/master/messytables/types.py#L124

It's much faster but does not support format guessing.
