IBM Corporation Copyrighted Files

I discovered 142 files in the decimaltestdata directory of the Python 3.7.8 product that are copyrighted by the IBM Corporation. There is no clear licensing for these files.

We would like to use these files, but there is no license in the product download that permits us to do so. Please provide terms of use for these files.

The tests come from here: http://speleotrove.com/decimal/

At the bottom of the page, it says that can direct inquiries to Mike Cowlishaw.
