Tiny-Touch NMPG Ender 3/Ender 3 Pro edition

**Description**
====================
This is a remix of TinyTouch NMPG, a very cost-efficent alternative to BLTouch and other commercial products - adapted for use on Ender 3/Ender 3 Pro with stock extruder assembly

Please note that even though this is a really interesting project for a weekend ***it might be hard to reproduce*** - minimal soldering skills, basic knowledge about firmware configuration (or will to learn about these things for one+ evening ;]) and a decently calibrated printer are required (problems are inevitable really)

You will need to tap M3 holes in body, flag and sensor cap, this will require good layer adhesion - but you can always try to re-melt plastic in holes using a screw and a solder iron in case something goes wrong (be careful about it tho!)

Although mount is BLTouch-friendly, it's not fully compatible with it - if you decide to swap to BLTouch at some point you will likely need a spacer between device and mount (TT is slightly taller)
