Add ability to generate individual pieces

[Neon22]

This is designed to print out a pattern for a full jigsaw to be cut efficiently on a lasercutter.
As such its actually quite difficult to cutout an individual piece.

I'd like to add an option to call the inkscape boolean ops one row/col at a time and thereby make each individual piece.
No use to a lasercutter but good if you want just isolated pieces.

hey,
fixed that separated piece generation task in my recent version successfully: https://gitea.fablabchemnitz.de/FabLab_Chemnitz/mightyscape-1.X/src/branch/master/extensions/fablabchemnitz/lasercut_jigsaw
its a bit slow but works
