Hard-coded paths in python scripts

[DanSGiesbrecht]

I noticed that some scripts for updating footprints have hard-coded paths:
@Misca1234, was this because only you were using them?

Hard-coded paths:

FPDir = '../../../../kicad-footprints/Package_DFN_QFN.pretty'
KISYS3DMOD = '../../../../kicad-packages3D'

FreeCadExe = '/c/users/stefan/Downloads/FreeCAD_0.17.11223_x64_dev_win/FreeCAD_0.17.11223_x64_dev_win/bin/FreeCAD.exe'`

Files containing hard-coded paths:

grep -rnw -e '/c/users/stefan'
FCAD_script_generator/QFN_packages/FindMissingLGA3DModels.py:87:FreeCadExe = '/c/users/stefan/Downloads/FreeCAD_0.17.11223_x64_dev_win/FreeCAD_0.17.11223_x64_dev_win/bin/FreeCAD.exe'
