Update to newer Klipper about klipper HOT 1 OPEN

@ale-chronics

@ale-chronics, you might find the attached bash script helpful. I've been using it for the past two years to keep my Klipper installation updated with the original Klipper while maintaining the Ender 6 patches from Desuuuu.

Just run the script in the directory where your ./klipper/ is located.
(Make sure you have a backup of your Klipper folder first.)

Also, remember that newer versions of Klipper may require updated firmware on the controller:
( cd klipper; make clean; make (might require make menuconfig, to update the .config file )

bash script :

#!/bin/bash
if [ ! -d klipper/.git ]; then
  git clone https://github.com/Klipper3d/klipper.git klipper
else
  echo "Klipper exists .."
fi

pushd klipper 


if ( git branch | grep desuuuu-ender6 -q ); then
  git switch desuuuu-ender6
else
  git branch desuuuu-ender6  
  git checkout desuuuu-ender6
fi

GIT_EDITOR=/bin/true git pull https://github.com/Klipper3d/klipper.git
GIT_EDITOR=/bin/true git pull -q -X ours --no-rebase https://github.com/Desuuuu/klipper.git

popd

from klipper.
