AMJ96 Support (#2651)

* Initial commit: Get things compiling

* port the custom matrix code

* Update readme

* make second layer fully transparent

* populate config.h identifiers with more correct information

* Add in switch backlight support

* Enable backlight LEDs, and change pin for RGB

* port TMK version over

* remove all that TMK stuff, it didn't work lol

* Updated readme

* Fix keymap

- Change KEYMAP to LAYOUT
- Adjust formatting of table

* Edit readme to reflect NOTES

* add info.json for QMK configurator support

* Replaced placeholder with MechMerlin

+# AMJ96
+
+The AMD96 is a 96 key custom keyboard with anodized aluminum case, twin usb ports, and support for backlight LEDs and RGB underglow via SMD LEDs.
+
+Keyboard Maintainer: [MechMerlin](https://github.com/mechmerlin)  
+Hardware Supported: AMJ96 
+Hardware Availability: Was previously available on a GB via [Flashquark](https://flashquark.com/product/amj96/)
+
+Make example for this keyboard (after setting up your build environment):
+
+    make amj96: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.
+
+## Notes
+- In-switch and underglow LEDs currently not supported.
