Add "extra_pyinstaller_args" arg to freeze()

[fredrikaverpil]

I'm looking to pass extra arguments to pyinstaller for my main app.

Right now, I'm using a build.py script which I execute like so: python build.py freeze_all

In my freeze_all function, I have the fbs.builtin_commands.freeze function to build my main app. But the builtin_commands.freeze function does not accept any arguments. I'm noticing that that freeze_windows, freeze_mac, freeze_arch, freeze_linux already takes the extra_pyinstaller_args argument, but the fbs.builtin_commands.freeze function does not. So in my mind, a very quick fix for this would be to make the fbs.builtin_commands.freeze function accept a new extra_pyinstaller_args argument which would be passed on to the freeze_windows, freeze_mac, freeze_arch, freeze_linux functions.

I wouldn't mind whipping up a PR if you think it's a good idea.

The background to why I am looking to do this is I wish to add a hooks folder, which I ideally want placed in my project's root (not in src/main/python). I would then want to pass the --additional-hooks-dir as an extra pyinstaller argument when building the main app.

This is so nice:

fbs.builtin_commands.freeze(extra_pyinstaller_args=['--log-level', 'DEBUG'])

And I can now choose if e.g. a commandline (main) application is showing its output :

fbs.builtin_commands.freeze(extra_pyinstaller_args=['--console'])
