Colors lost when converting SVG to PLT

[macfanmr]

Maybe this is expected, or maybe PLT has a limited color space or something, but I'm outputting SVG files with RGB colors assigned to the lines and as far as I can tell when I open them into my laser software, they're all one color, the default color. I see UC has support for colorspaces and I tried to find documentation on that, but was unsuccessful.

I've seen this on OSX, Win7, and Ubuntu 20.04
