Subfolder of zip file has been removed

The 'Code-Point Open' subfolder no longer exists inside the zip, so the root var can be set to an empty string (or removed altogether).

The 'data_name_format' is correct in the Git repo, but incorrect (the 'CSV' subfolder is missing) when I download this using pip. Not sure why that is.

Otherwise, this is a very useful package - I was going to write something similar myself until, surprise surprise, I discovered someone had already taken care of it. Python is great like that :-)
