Libre Computer Renegade Board Case

This is a slightly tweaked version of Firefly Libre Computer Renegade Board Case by @gsansone4. My remix is specifically for the Libre Computer variant of this SBC (which is apparently not quite the same as the Firefly). I only made a couple changes: added a notch for the IR sensor on the Libre and closed up the USB 3.0 cutout a bit. Thanks to the original designer @Normand for this really nice case and to @gsansone4 for his mods!
