Extension based upon the eggbot_hatch extension from https://github.com/evil-mad/EggBot.
Creates plottable hatches (simple, cross-hatch, in a single path or separate) in all closed objects in the drawing or in all selected objects.
Improvements include:
* Updated to work with Inkscape 1.2 and higher
* Simplified a portion of the code
* Added the option to choose units for the hatch distance and inset
* Only depends on inkex now, which makes installation much easier
License: GPLv2 or higher
Version 4.0: Clarified the meaning of the distance. It is not an actual inset, but more of a safety distance when using a pen plotter.
