Personal user space and CRKBD R2G keymap (#15888)

* r2g folder groundwork

* Default mb keymap featuring mb logos

* Migrate Oled to keyboard folder

* Move rules configs to support config better

* update readmes

* Liscnece update

* Update config and fix issues caused by redef errs

* funciton name adjusts, define specific rgb modes

* move default oled font to postconfig

* update oled in line with develop merge

* fix return value

* Add some default rgb matrix defines

* del ugfx

* remove #include <stdio.h>

* create personal keymap for r2g

* reduce firmware size

* change keymap to follow physical layout

* remove RGBlight config lines to make both sides work (@Dasky on MechboardsUK Discord)

* strip down configuration, similar to crkbd/r2g:mb_via

* remove wrong oled code overwriting the r2g one

* broken code with RGB matrix (briks right side)

* remove high max brightness limit

* caps lock tap dance and RGB indicator for active caps lock

* fix caps lock led on right side

* add test macro

* remove latex macro which is too slow

* move caps lock tap dance to RALT and add space cadet shift

* switch CTL with ALT in first layer

* add tap dance for ESC/DEL

* space cadet tap dance with caps lock; shift works by needs a short pause

* add space cadet tap dance with caps lock on the right; shift works by needs a short pause and does not hold

* make more keys transparent

* enable auto shift and use logo on both oleds

* add user oled logo, slows down linking considerably

* oled name

* add arrow keys in usual configuration and add linear configuration to symbol layer

* add unicoede support

* add accents

* update to latest version

* add colemak dh layer

* report auto shift timeout

* define layer name shorcuts correctly

* disable VIA to enable more layers

* enable NKRO

* move some rules and unicode to user space

* move oled and tap dances to user space

* move tap dances fully out of keymap

* expand unicode map

* fix unicode code

* revert changes to r2g, make it equal to merged code

* revert changes to r2g, make it equal to merged code

* clang-format userspace

* clang-format config file

* Update keyboards/crkbd/keymaps/rmeli/keymap.c

* replace define with enum

* add licenses
