SpotMicro v2

Based on the increasingly popular [Spot Micro design](https://www.thingiverse.com/thing:3445283), I made a branch of it, to to improve a few points:

- All nuts and bolts were replaced with self tapping screws (way easier and faster to assemble and open/close covers to access electronics)
- Thanks to the self tapping screws change, no more gluing of any part!
- The foot bigger is now bigger on the inside, and the wrist smaller (no noticeable from outside, but will have better elasticity)
- Changed the servo horn to the ones that come with the servos PDI-HV5523MG
- Made a tester for those servo horns so anyone can check if they would fit before printing a leg section
