DSN export problems with mounting hole.
# Steps to reproduce
1. I load up a PCB into KiCAD and then export it to Spectra DSN. mount hole produces a very large footprint.
2.
This was produced today after loading a DSN made on 13/4/2023 using 7.0.1, into FreeRouting. I took a snapshot of the design on the 13th.
Today I reloaded that old version into 7.0.2 and reexported and then loaded it into FreeRouting
The blue overlapping circles are centred on the mounting holes.

I have tried this with the standard issue 3.5mm hole as well as this slightly custom one and the issue is the same.
