installation for MDBT42Q

got it running at the end (HIP HIP HURRAY)
IMHO at the end its all about PYTHON version hell. No idea, why python3.6 did not accept nrfutil 6.1.0. Testing with TensorFlow and Opencv might have been the root of problems
I'm pretty sure people with more knowhow around python could explain. People like me, that want to compile Espruino only, have to walk through dessert to find some water_

This is my way to find water:

• installed python3.8
  
• added an alias for python to python3.8 in .bashrc for user espruino
  
• logged out and logged in again
  
• installed pip with python -m pip install pip did this because pip before still pointed to python3.6. Therefore all installation had been done to .local/lib/python3.6
  
• installed nrfutil with python -m pip install nrfutil
  now I've a folder ~/.local/lib/python3.8/site-packages.And nrfutil is installed in version 6.1.0
  Next switched to folder with Espruino-installation and called
  
• RELEASE=1 DFU_UPDATE_BUILD=1 BOARD=MDBT42Q make >tmp/stdout 2>tmp/stderr
  and it worked fine. I've got my zip for uploading to MDB42Q board
