Enh/main function

[timdiller]

Add a command line interface for directory_tree. The use case is installing something with the same utility as tree in an environment where pip install is available but not sudo apt install.

To make the packaging a little more Pythonic, I renamed src to directory_tree and added __init__.py and __main__.py with argparseing so that it can be invoked from the command line:

❯ python directory_tree -L 2 -I '__pycache__' 'directory_tree.egg-info'
