nrfutil fails to run with python3

[Terstegge]

I just tried to install nrfutil using
pip3 install nrfutil,
but after running the tools I get an error message:
Traceback (most recent call last):

Installation was successfull, though...

This is due to a too loose dependency setting on protobuf. Result of pipdeptree -p nrfutil (pipdeptree is a pip package):

nrfutil==6.1.0
  - click [required: Any, installed: 7.1.2]
  - crcmod [required: Any, installed: 1.7]
  - ecdsa [required: Any, installed: 0.17.0]
    - six [required: >=1.9.0, installed: 1.14.0]
  - intelhex [required: Any, installed: 2.3.0]
  - libusb1 [required: Any, installed: 1.9.2]

    - wrapt [required: Any, installed: 1.12.1]
  - piccata [required: Any, installed: 2.0.1]
  - protobuf [required: Any, installed: 3.6.1]
  - pyserial [required: Any, installed: 3.5]

    - pyserial [required: Any, installed: 3.5]
  - pyyaml [required: Any, installed: 5.3.1]
  - tqdm [required: Any, installed: 4.61.0]

Protobuf here is 3.6.1 and works. You will see that if your protobuf is too old, you'll get this error.
