VaryTempWithHeight reacts to Z-hops

[bradjshannon]

If you use a Z-hop after retractions, the extruder's Z-height during a hop will trigger the script.

This is a problem if the Z-hop is set to any distance greater than a single layer height. With the script expecting 0.2mm layers, and a Z-hop of 1mm (extreme but possible), the script will change the temperature 5 layers earlier than desired.

Sorry, I totally forgot about this until now. Interesting problem, not sure there would be a good way to detect that a z hop is different than a regular z change. The script itself doesn't assume anything about layer height as far as I'm aware, it just checks every layers Z value, and changes the temp when it hits a new z threshold based on the settings entered.

If @bradjshannon can add some gcode examples for cura's Z-hops, I will attempt to code a fix.
