Keymap: add new keymap (#4127)

* an attempt at own layout

* typematrixed dvorak

* columns shifted

columns shifted out, second pinky column moved to the inside.

* Update users/romus/romus.h

* code cleanup

Changes requested by Drashna + Tap Dance enabled

* Fixed EOF

Fixed the no newline at the end of file alert.

* rgblight fight eeprom writes

* rgb code simplification

* Update users/romus/README.md

* Update quantum/keymap_extras/keymap_slovenian.h

+# overview
+
+ this is a modified version of let's split keyboard from bbaserdem. i don't like standard dvorak overuses right pinky
+ so i shifted the columns out. i'm not sure if this is any good, time will tell.
+
+ i have ortholinear let's split eh, which share a lot of functions with other ortholinear keyboards.
+
+# layout
+
+i use dvorak with an unorthodox off layout.
+if you wanna grab my code, and you used a layout with a persistent base
+layer change, change it to layer 0 before proceeding.
+
+# layers
+
+* **dvorak**: base layer,with dvorak layout.
+* **alternative**: has alternate characters.
+* **game**: toggled from *function*, comfortable for gaming use.
+* **numeric**: has numericals and symbols. can be locked.
+* **function**: layer has media and function keys.
+* **mouse**: manipulates mouse. can be locked.
+* **music** allows playing sounds.
+
+# functionality
+
+* **rgb backlight**: with layer indication, and ability to change base layer lighting mode.
+* **secrets**: by placing a secrets.h, and not tracking it, passwords can be stored.
+* **mouse**: mouse emulation, complete with diagonal keys.
+* **turkish**: an altgr-like overlay that allows some non-common letters, in unicode.
+
+i suggest checking out how i enabled turkish keys,
+how i planned out rgb lighting,
+and my mouse implementation;
+they might offer some insight into fringe user cases.
+
+# issues
+
+all features are too big for the 32kb bootloader.
+offenders are audio and rgb lights; it comes down to one or the other.
+
+~the proton board, and rev 6 might fix that.~
+
+# credits
+
+this is a modified version of let's split keyboard from bbaserdem who has previously written his keymap by himself before, but rewrote it here.
