munzig - really small font for 3D printing (3.5mm height)

created an otf font that can be printed with one line from a 0.4mm nozzle. character height is 3.5mm

this is work in progress and i'll be adding more characters as i use them or if requested.

heavily inspired by this character set: https://www.uantwerpen.be/nl/personeel/geert-keteleer/manuals
but in a usable format

openscad:
```
use ;

text(text="THE QUICK BROWN DOG JUMPS OVER THE LAZY FOX", size=6, font="munzig");
```

sliced in prusaslicer with default settings should work.
