[Keyboard] Add nullbitsco SCRAMBLE (#11078)

* Add SCRAMBLE

* Make requested changes to PR

* Add all layers to VIA keymap

Implement drashna's PR feedback in order to avoid random data within the layers in VIA.

* Make requested changes to PR

Implement fauxpark's PR feedback to clean up readme.md and rules.mk.

* Make changes based on PR feedback

-Changed VIA layers to enum
-Added info on how to enter the bootloader to readme

+
+![SCRAMBLE](https://nullbits.co/static/img/scramble1.jpg)
+
+A 6-switch key tester macropad built by nullbits. [More info at nullbits.co](https://nullbits.co/scramble/)
+
+* Keyboard Maintainer: [Jay Greco](https://github.com/jaygreco)
+* Hardware Supported: SCRAMBLE Rev1
+* Hardware Availability: [nullbits.co](https://nullbits.co/)
+
+Note: If you are seeing issues with MacOS and keyboard hangs after sleep, make sure `NO_USB_STARTUP_CHECK = yes` is set in your rules.mk.
+
+In order to enter the bootloader, hold switch #6 while plugging in the USB cable. The LED will stay on to indicate that it's in DFU mode.
+
+Flashing example for this keyboard:
+
+    make nullbitsco/scramble:default
+
+See the [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) and the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information. Brand new to QMK? Start with our [Complete Newbs Guide](https://docs.qmk.fm/#/newbs).
