Package does not install required dependencies

[nralbers]

Installing wonderwords does not install it's actual dependencies. The contents of requirements.txt should be added to setup.py as package dependencies.

To Reproduce Steps to reproduce the behavior:

1. pip install wonderwords
2. wonderwords -s
3. ModuleNotFoundError: No module named 'rich'

Expected behavior package runs

• OS: ubuntu 22.04

Rich is used only for the command-line interface, so I set it as an optional dependency. To install command-line dependencies, use pip install wonderwords[cli].
