handwired/gamenum Refactor, Configurator support and readme cleanup (#4563)

* handwired/gamenum: refactor

- layout macro KEYMAP renamed to LAYOUT
  - white space changes for alignment
- default keymap
  - now uses #include QMK_KEYBOARD_H
  - updated layout macro names
  - white space changes (for readability)

* handwired/gamenum: Configurator support

* handwired/gamenum: readme cleanup

- renamed file to lowercase
- updated to match current QMK template more closely
- edits to reflect the other changes in this PR

 This is the default layer for the gamenum. It's generally easiest to just copy this and change things as you see fit. Keep in mind that at least 1 button on the pad has to be used to switch to the next layer in the stack or you will be stuck in that layer FOREVER! D:

 This is the code for the KC_FN1 button. Notice how we check against what key is pressed in the case and then set pin C6 low and pin D4 high. Adjust this as you see fit.

-## Quantum MK Firmware
-
-For the full Quantum feature list, see [the parent readme.md](/docs/README.md).
-
-## Building
-
-Download or clone the whole firmware and navigate to the keyboards/handwired/gamenum folder.
-Read the README.md for the qmk repository on how to set up your developer enviroment to build your firmware with.
-Building firmware on Windows can be a bit of a hassle. Linux is a lot easier to use if you have some experience with it. A raspberry pi will already be able to build the firmware for you.
-Once your dev env is set up, you'll be able to type `make` to generate your .hex - you can then use AVRDudess to program your .hex file.
-
-### Default
-
-To build with the default keymap, simply run `make`.
-
-### Other Keymaps
-
-To build the firmware binary hex file with a keymap just do `make` with `keymap` option like:
-
-```
-$ make keymap=[default|jack|<name>]
-```
-
-Keymaps follow the format **__keymap.c__** and are stored in folders in the `keymaps` folder, eg `keymaps/my_keymap/`
-
-
