@hugovk, thanks for adding the function test_guess_file_type()!

My contribution here is insignificant, and I think it would be more fair if you will add your name instead of my.

(But if the name of the author of the pull request is required, perhaps, Sasha “Nelie” Chernykh instead of Kristinita would be better).

Thanks.
