Sorry for my late response. Shedules are getting a bit tight here. After the weekend my day should be much more free. I'll keep you posted.
Getting the svgs to work is really no problem at all – just a bit of work. Making the actual package will take a bit more practice to port over to python. I'll wrap my head around that after creating all the images.
Regarding Spice: I'll really have to do some research here. I do not have any knowledge at all about that – although the corresponding course was only two years ago.
