Remove deprecated distutils functionality

[matthewfeickert]

distutils is deprecated in Python 3.10+, as noted in the pip v21.3 release notes

On Python 3.10 or later, the installation scheme backend has been changed to use sysconfig. This is to anticipate the deprecation of distutils in Python 3.10, and its scheduled removal in 3.12. For compatibility considerations, pip installations running on Python 3.9 or lower will continue to use distutils.

To prevent bugs in the future that will cause tests to break, we should switch the distutils functionality

from distutils.dir_util import copy_tree

Lines 39 to 43 in f35c780

	def create(name, path):
	template_path = pkg_resources.resource_filename(
	"recastatlas", "data/templates/helloworld"
	)
	copy_tree(template_path, path)

to setuptools (I think it is setuptools).
