LICENSE being installed to the wrong path

[algorythmic]

As specified currently in setup.py with

config['data_files'] = [('', ['LICENSE'])]

this gets installed right into sys.prefix (or causes an error with homebrew python):

$ pip install anytree
Collecting anytree
  Using cached anytree-2.8.0-py2.py3-none-any.whl (41 kB)
Requirement already satisfied: six>=1.9.0 in /usr/local/lib/python3.8/site-packages (from anytree) (1.15.0)
Installing collected packages: anytree
ERROR: Could not install packages due to an EnvironmentError: [Errno 13] Permission denied: '/usr/local/LICENSE'
Consider using the `--user` option or check the permissions.

Per pypa/setuptools#1536 this should not be necessary, rather license_file can be specified instead.
