Suggest pipx for installation. Fix `avp` command.

Allegedly the gui_scripts is only different from console_scripts on Windows, and it has the effect of hiding the console window. This seemed to make the `avp` entrypoint crash, possibly because the app already contains its own logic for hiding the console window(?). I've tested this on Windows 11 and it seems to work better using console_scripts.
