Installer doesn't put capirca command in ~/.local/bin

The installation instructions say that after installation one can invoke capirca as `~/.local/bin/capirca`. However, the installer doesn't install anything in ~/.local/bin. This applies both when installing from a clone of the current git master branch and when installing from PyPI via pip. In both cases, the installation finishes without error, but ~/.local/bin/capirca does not exist:

```
$ python setup.py install --user
running install
running bdist_egg
running egg_info
creating capirca.egg-info
writing capirca.egg-info/PKG-INFO
writing dependency_links to capirca.egg-info/dependency_links.txt
writing entry points to capirca.egg-info/entry_points.txt

Using /home/jhaiduce/.local/lib/python3.10/site-packages
Finished processing dependencies for capirca==2.0.4
$ capirca
bash: capirca: command not found...
$ ls ~/.local/bin/capirca
ls: cannot access '/home/jhaiduce/.local/bin/capirca': No such file or directory
```

But the capirca package is successfully installed in ~/.local/lib/python3.10/site-packages:
```
$ ls /home/jhaiduce/.local/lib/python3.10/site-packages/capirca*
