Keyboard: Add support for Diverge TM2 (#3829)

* pulling in diverge tm2 from staging branch

* cleaned up comments, docs, licenses

* refactored apparent grid to make 2u spacebars more obvious

* various delinting from noroadsleft review

* most of drashna's feedback responded to

- lots of lint swept
- used more modern tri-layer functions
- still need to adopt modern split support.

* switch to common split code. remove comment cruft

* tapping force hold makes LT way more usable for rapid ,  sequences

+Based on the standard Planck layout with a few changes:

+* Dedicated movement and mouse layers.
+* Top and middle row swapped in `_RAISE` and `_LOWER` because I never use F-keys.

+# diverge tm2
+
+A 4x6x2 split ortholinear keyboard with 2u spacebars like the Levinson (similar to Let's Split). Made by [Unikeyboard](https://unikeyboard.io).
+
+Keyboard Maintainer: [IslandMan93](https://github.com/islandman93) and [xton](https://github.com/xton)  
+Hardware Supported: Pro Micro  
+Hardware Availability: [Diverge TM2](https://unikeyboard.io/product/diverge-tm/)
+
+Make example for this keyboard (after setting up your build environment):
+
+    make divergetm2:default
+
+See the [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) and the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information. Brand new to QMK? Start with our [Complete Newbs Guide](https://docs.qmk.fm/#/newbs).
+
+# Flashing the first time
+
+Disassemble the case so you have access to each Pro Micro. Flash each half with QMK Toolbox by connecting the USB cable and shorting RST and GND. After that, just use the soft reset key on your respective layout to reflash both halves. 
+
+# Reflashing Animus
+
+Reflashing the stock firmware is pretty easy. Just follow the same steps in the [original guide](https://imgur.com/a/8UapN). You will have to manually reset the Pro Micro (by shorting the GND and RST) during the upload step. Then reapply your keymap through Arbites.
