Implement a group_by_owners function that:

    Accepts a dictionary containing the file owner name for each file name.
    Returns a dictionary containing a list of file names for each owner name, in any order.

For example, for dictionary {'Input.txt': 'Sandy', 'Code.py': 'Stan', 'Output.txt': 'Sandy'} the group_by_owners function should return {'Randy': ['Input.txt', 'Output.txt'], 'Stan': ['Code.py']}.
