Octagon V1 Support (Port) (#2184)

* Preliminary commit for Octagon V1 support

This is essentially a cp -R v2 v1 with a few things changed to
get it to compile and build.

* The Octagon V1 supports up to 84 keys as opposed to the V2 which
supports up to 86. This commit changes the keymap to match it.

* Temporary default keymap just to get things to compile

* Update readme file

* Fix switch matrix

* Fix underglow lighting option

* Fix keymap to take care of shifted columns

* Fix keymap formatting

* Remove un-needed files left over from rasmusx

* Make Octagon V1 have its own keymap directory with default keymap

* Make Octagon V2 have its own keymap directory with default keymap

* Cleanups and readme edits

+# Duck Octagon V1
+
+Non official firmware for custom Korean keyboard with 75% key layout made by Duck.  
+Group buy was run October 2014 via [geekhack](https://geekhack.org/index.php?topic=65036.0) 35 keyboards total. 
+
+Keyboard Maintainer: [MechMerlin](https://github.com/mechmerlin)  
+Hardware Supported: Duck Octagon PCB Ver 1.0, Atmega32u4  
+Hardware Availability: Wait until GB of the next revision
+
+Make example for this keyboard (after setting up your build environment):
+
+    make octagon/v1:default
+
+See [build environment setup](https://docs.qmk.fm/build_environment_setup.html) then the [make instructions](https://docs.qmk.fm/make_instructions.html) for more information.
+
+## Hardware Notes
+
+The Duck Octagon V1 PCB consists of:
+
+### Microchips
+2 74HC237D 3-to-8 line decoders
+1 Atmega32u4 microcontroller
+2 WS2811 LED controller
+
+## Notes
+Thanks to Ralf Schmitt for previous implementations in his [TMK fork](https://github.com/xauser/tmk_keyboard/tree/xauser/) and few helping words.
+
+Based heavily on Rasmus Schults [Duck Lightsaver QMK Port](https://github.com/qmk/qmk_firmware/tree/master/keyboards/lightsaver)
