Add support for Slic3r++

[guestisp]

This add supports for Slic3r++ by Supermerill just a strangeness (it's the same for all slicers): the object max height shown will report the Z max height not the object height. In example, if you have a end gcode that raise Z axis after the print to Z max (in example 250mm) , the object max height is reported as 250mm this because you are looking for the higher number found in G1 Z gcode command.

[Stephan3]

pls provide a example gcode. I will look into it. Thanks.

I've extracted the comments from a gcode made with Slic3r++ (now SuperSlicer, maybe a new fix is needed)

[exxperto]

SuperSlicer already done. But sometimes it's got not a correct print height in DWC2

[guestisp]

I've look at current changes and they seems identical to mine in this PR, so probably, superslicer is already supported. But I would keep the Slic3r++ version too, in case someone is still using Slic3r++ before renaming.
