[Keyboard] Keyboardio Atreus (#10570)

* Initial support for the Keyboardio Atreus

Many thanks to noroadsleft for reviews & suggestions.

* Add QMK Configurator layout support

* Update the fn layer of the Keyboardio Atreus to the new layout.

Previously this was using the Classic Atreus layout.

* Implement noroadleft's changes from #8492

* Follow Erovia's recommendations

qmk/qmk_firmware#8492

* Correct braces

* Change correct rules.mk

* Remove comments

* Fix BOOTMAGIC_ENABLE

I had edited the wrong file earlier.

* Remove comment

* Updates rules.mk

Thank you noroadsleft.

+# Keyboardio Atreus
+
+![Atreus](https://atreus.technomancy.us/i/atreus2-mug.jpg)
+
+A small mechanical keyboard that is based around the shape of the human hand.
+
+* Keyboard Maintainer: [Keyboardio](https://github.com/keyboardio)
+* Hardware Supported: Keyboardio Atreus
+* Hardware Availability: https://www.kickstarter.com/projects/keyboardio/atreus
+
+These configuration files are specifically for the Keyboardio Atreus, a
+collaboration between [Phil Hagelberg](https://github.com/technomancy) and
+[Keyboardio](https://github.com/keyboardio). The keyboard is currently on
+Kickstarter, and will come fully assembled.
+
+Make example for this keyboard (after setting up your build environment):
+
+    make keyboardio/atreus:default
+
+Flashing example for this keyboard:
+
+    make keyboardio/atreus:default:flash
+
+*Unlike the TMK firmware, these commands should be run from the root of the repository, not the directory containing this readme.*
+
+To flash new firmware, the keyboard needs to be in bootloader mode. To do that,
+one needs to hold the bottom left key (`Esc` by default) and reset the
+keyboard - either via a macro, or by sending a hang-up signal to the keyboard
+device, or by pressing the reset button on the bottom with a pin.
+
+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).
