[Feature request] temperature ladder

[lacklustrlabs]

I wanted to use a Customizable Temp Calibration Tower. Cura has a TweakAtZ feature that works, but the problem is that TweakAtZ settings are not saved.

So instead I hacked your code to do something similar: process_g_code.py -i i.gcode --temperatureladder "3:200,13:202,23:204,33:206,43:208,Zn:Tn" -o o.gcode

~~The hack requires that a temperature is 'injected' at each layer before the temp ladder is applied:~~ process_g_code.py -i i.gcode --inject t200.gcode zheight 3 -o o.gcode

The code is still a bit rough around the edges (was a long time since I did anything python)

Question is, is this something you want to include (and fixup proper) in the repository?

@lacklustrlabs sorry but how do i use this python code to edit the gcode? i am looking for similar plugin/script/app for getting current line of gcode which is being printed
