Small utility to nest multiple SVGs files into a single one, trying to minimize the empty wasted space. This is usually useful for lasercutting projects.

For now, the nesting is ultra basic:

• Rectangle packing using the rectpack library, considering the bounding box of the paths
• files with a single path in it seem fine.
• files that contain multiple paths might
• units are assumed to be mm
• Nesting on multiplate plates|bins is not yet supported
• All paths are brutally styled: removing the fill and putting the stroke to red with 0.1 width
  • This was done because I was nesting .svg files exported by OpenSCAD

The API to call from Python is minimal:

from svgnest import nest
files = {
  'part1.svg': 1,
  'part2.svg': 2
}
// nest in a 600x300 mm plate, saving to combined.svg 
nest('combined.svg', files, 600, 300)

each file can be added once or multiple times to the plate by specifying in the files input dictionary.
