Include python dependencies in build

As a temporary measure, I added some buttons that call the functions in a [dependency installer](https://github.com/KitwareMedical/lungair-desktop-application/blob/0ce323f94bc3876c3cb706eee3557d92d8ad4781/Modules/Scripted/Home/HomeLib/dependency_installer.py).

Eventually it would be good to include these dependencies in the build system and have them available automatically after building and after packaging.

Start by reading Modules/Scripted/Home/HomeLib/dependency_installer.py to identify the Python dependencies currently installed by the temporary buttons. Then locate the application's build and packaging configuration, which the issue does not name, and determine how those dependencies should be included. Done means a fresh build and packaged application provide the dependencies automatically.
