app2exe command doesn't suport space in app path

[ViviMine]

Hey,
I was trying to convert a .pyxapp file into a .exe, but an error occured:

'G:\Mon' n’est pas reconnu en tant que commande interne
ou externe, un programme exécutable ou un fichier de commandes.

To simply translate that, it don't handle the space beetwen G:\Mon and the rest of the path. Just a simple fix to do I think, thx

Description
pixel's app2exe verb doesn't produce a file if the path that follows him include a space in it, at least under Linux and Windows

Steps to Reproduce

• Open a terminal under a Linux distro with Python, version 3.8 or higher, and the pyxel and pyinstaller module.

• Type:

mkdir -p "simple repro" && echo 'import pyxel;  print(pyxel.VERSION)' > "simple repro/repro.py"
pyxel package "./simple repro" "./simple repro/repro.py"
pyxel app2exe "./simple repro.pyxapp"

• Observe the pyinstaller error on add-data argument.

Expected Behavior
A 'simple repro' executable should have been produced in the current working directory.

Actual Behavior
pyinstaller throw an error regarding the value of the add-data command line argument passed to it.

Environment
OS: Linux (Archlinux rolling), Windows 10, Wwindows 11, perhaps macOS
pyxel version: 2.4.10

Additional context
I am following up on this issue and I observe it on Linux distributions and Windows 10 & 11. By tightening the issue with the presented reproduction case, I concluded that the construction of the command line of pyinstaller does not properly enclose the arguments, leading the shell parser to think that an argument ended when there is a space.

Workaround
Look at 66dc601
Or develop something that replaces the building of the pyinstaller command line with the #use of another pyinstaller API
