[Keymap] Neo2 for ErgoDox on MacOS US QWERTY / ABC Extended keymap (#5862)

This is a Neo2 inspired layout that is meant to be fully usable on
MacOS when used with the default US QWERTY/ABC Extended keymap.

Neo2 layers 1-4 have been almost fully implemented in hardware.
Layers 5 and 6 (greek and mathematical symbols) have been left
out for now as most of them aren't available on the default
keymaps.

Layer toggling for layer 3 on the right hand side utilizes a
tap-toggle approach that is a combination of MO & LT macros.
This is required to allow sending Y when tapped, @ when tapped
while the SHIFT modifier is active and support momentarily
toggling the layer while the key is held.

+# Neo 2 for ErgoDox on QWERTY
+
+# Description
+
+The Neo layout is an optimized German keyboard layout developed by the 
+Neo Users Group, supporting many Latin-based alphabets. The positions 
+of the letters are not only optimized for German letter frequency, 
+but also for typical groups of two or three letters.  English is 
+considered a primary target as well. 
+
+The design tries to enforce the alternating usage of both hands to 
+increase typing speed  and incorporates ideas from de-ergo and other 
+ergonomic layouts. High frequency keys are placed in the home row. 
+The current layout Neo 2.0 has unique features making it suited for 
+many target groups such as programmers, mathematicians, scientists or 
+LaTeX authors.
+
+Neo is grouped into six layers, each dedicated to a special purpose.
+
+# Layers
+
+At the core this is a Neo 2.0 layout adjusted for the Ergodox Infinity. 
+The keymap is laid out expecting a macOs using the US QWERTY or ABC 
+Extended layout. 
+
+[Layer 1](#layer-1) Lowercase, upppercase and typographical  characters
+
+[Layer 2](#layer-2) Special characters for programming
+
+[Layer 3](#layer-3) WASD-like movement keys and number block
+
+[Layer 4](#layer-4) Greek characters
+
+[Layer 5](#layer-5) Mathematical symbols and Greek uppercase characters
+
+[Layer 6](#layer-6) Ergodox Infinity US QWERTY layout
+
+[Layer 7](#layer-7) Function keys
+
+## Legend
+
+ * Keys marked with `----` are dead keys.
+ * Blank keys are transparent and fall through to lower levels.
+
+## Layer 1
+
+This layer implements NEO layers 1 and 2.
