Create a unique folder when not specified by the user

[samwaseda]

I thought it might be neat to automatically generate a working directory:

from pyiron_snippets.files import DirectoryObject
directory = DirectoryObject()
print(directory.path)

Output: PosixPath('data_9d2d9cc5da624d4da95455a12c8cb490')
