Add tidiers for car::durbinWatsonTest objects

Trying to resolve #266

You need to add car to Suggests in DESCRIPTION. Probably the best way to do this is with the usethis package: usethis::use_package("car", type = "Suggests") I believe. Then you'll want to use library(car) in the test file, or refer to the test function with a car:: prefix.

Does that help?

Also I think it would be best to just implement a glance method, and no tidy. tidy is meant to be used on model components, but here we can only really summarize the whole model, so glance is the way to go.

I noticed that the htest tidiers make the tidy and glance the same, so that's what I did for this one as well.

Okay, that's fine then!

@karldw I think this resolves #266
