[solution] psutil missing in build for macOS Intel, ptx2pdf version 3.0.39

Start with the packaging configuration for the macOS PTXprint.app build and inspect the import path through ptxprint/multiprint.py, where the failure occurs. Check how PyInstaller handles psutil and add the required packaging entry if needed. Done means rebuilding the Intel macOS app and launching it without the ModuleNotFoundError.

PROBLEM:

mm@MMs-iMac ptx2pdf-3.0.39 % ./dist/PTXprint.app/Contents/MacOS/PTXprint-app 
Adding .../_PTXprint
