[Keymap] userspace and keymap for rupa (#9786)

* first iteration of my keymap

* * move to userspace
* "script" modes
* keymap bling

* OM and RUPA keys

and tryin to micro-optimize in process_records.c

* woops

swap shifted rupas
forgot to add codepoint for OM

* Apply suggestions from code review

Co-authored-by: Drashna Jaelre <drashna@live.com>

* add call to process_record_keymap, per review

* fall through to process_record_keymap

* license headers

+# rupa's TADA68 layout
+
+i've swapped the lufa-ms bootloader for caterina
+
+most everything is in my userspace dir
+
+console mode is on, and there's barely any room left!
+
+* win/alt -> alt/cmd
+* alt/fn -> fn/alt
+* grave escape, with alt override
+* caps is another fn key, CAPS on fn-rctl
+
+fn layer:
+  * no wasd arrows
+  * rotate mute/vol
+  * backlight -> breathing, step, toggle
+  * swap home and ins
+  * unicode chars sprinkled around
+  * script mode!
+  * (one-shot) right versions of shift/ctl/alt/gui (not working quite right yet)
