Convert EAGLE files to XML

[electron271]

I know that this won't benifit MI much, but considering that MI is shutting down (bye pichenettes, I'll really miss you, you have been an amazing figure in the Eurorack community), I think converting them to XML would make it easier for people to study the MI products (this way you can import into something like KiCAD).

I have EAGLE free on my other computer, so I can try converting some of them myself and then open a PR

@pichenettes, I'll install EAGLE on my computer and make a PR for this issue, I'll send the number when I start it

KiCAD files are also an option.
