Can't perform input shaper tuning due to bad klippy-env

[HitLuca]

I just finished tuning my klipper input shaper, but not without issues. Looks like the provided python env in ~/klippy-env has issues, more specifically it returns errors when running klippy-env/bin/pip install numpy (something similar to no module named packaging.utils from pip._vendor.packaging). This issue made me try everything to get it working, but at the end the simplest solution was to recreate it with

pip install virtualenv
rm -r /home/klippy/klippy-env
virtualenv --python="/usr/bin/python2.7" klippy-env

after those commands the numpy installation succeeded!

Just to ease the following steps, make sure to install numpy and matplotlib on the system interpreter too using pip, otherwise you'll need to run the klipper/scripts/calibrate_shaper.py /tmp/resonances_#_*.csv -o /tmp/shaper_calibrate_#.png command by specifying the python interpreter in klippy-env

just added numpy & matplotlib as global pip installs, with klipper now also supporting python3 this s a lot more straightforward

just reopened to make sure the release builds, then will close and reference in release notes...
