Added additional X axis pause functionality

[empege]

Hey Simon,

I am using GoPro with remote controller to shoot images for a timelapse, on Ender 3 V2.

The issue with the remote is that it will shoot an image only when button is clicked and released immediately. So, if I pause more than 400, 500ms, meaning the button will be pressed for that amount, it will not shoot an image.

I made a third g code update, so that head moves to X axis (second), and immediately to third position. Like this, it will press the button and move a bit back to release it, but stay paused.

I do not know python, so I am sure you can make this better code vise, if you think this could be usefull for others that have the same need like me. For me this works though, but surely it can be upgraded in a better way.

Thanks a lot for this script!
