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

+#     automatically to create a 32-bit value in your source code.

+#     This will be an integer division of F_USB below, as it is sourced by
+#     F_USB after it has run through any CPU prescalers. Note that this value
+#     does not *change* the processor frequency - it should merely be updated to
+#     reflect the processor speed set externally so that the code can use accurate

+#     differ from F_CPU if prescaling is used on the latter, and is required as the
+#     raw input clock is fed directly to the PLL sections of the AVR for high speed
+#     clock generation for the USB and other AVR subsections. Do NOT tack on a 'UL'
