This reverts commit ed914160d7e27e6412d2c7c5c1c4fa0a04838667.

* Fix default keymap for Eagle

* Enable extra keys for audio control support

* Modified timings in indicator_leds to accomodate the WS2811S chips on the Eagle/Viper2 PCBs at 800kHz with a 16mHz clock
Modified the backlight settings to not interfere with the default RGB underglow code from QMK
Modified the order of the LEDs in the LED status bar at the top of the Eagle/Viper2 PCBs (3,2,1,6,5,4,8,7 order)

* Cleaned up indicator code to remove unused functions as the RGB underglow uses the
default driver provided by QMK

Commented out backlighting code in v2.c

* update readmes to reflect profanum's awesome contributions and fix typo in make instructions

* Remove custom RGB logic and just rely on QMK RGB underglow. We'll leave the backlighting in place for now

+MechMerlin's Duck Eagle V2 Layout
+======================
+
+This is the preferred 60% layout used by u/merlin36, host of the MechMerlin YouTube channel.
+
+![Duck Eagle V2 Layout](https://imgur.com/FRcsmJc.png)
+
+## Keymap Notes
+- Highly influenced by the KBP V60 and WKL B.Face standard layouts
+- Does not support any form of inswitch lighting as Merlin hates them.
+- Arrow toggle switch is FN + Space
+- Reset is FN + R
+
+### Build
+To build this keymap, simply run `make eagle_viper/v2:mechmerlin` from the qmk_firmware directory.
