[Keyboard] Add Budget96 by Donut Cables (#5550)

* initial commit of budget96

* non logic changes

* add my name to readme

* update matrix.c

* make the matrix representation of the layout macro

* fix up LAYOUT macro

* add missing character

* initial keymap commit

* put KC_NO where they belong

* basic keymap

* fix matrix row and col definition

* The diagram I was sent and the pins used I was sent were in opposite order from each other. This should fix the issues

* update the readme

* change up manufacturer for budget96

* update copyright date

* fix up the switch matrix and provide a keymap

* forgot the keymap

* other matrix fixes

* missing a few keys in the switch matrix

* messed up the row tracing

* tweak keymap a bit

* use a lower case k

* fix spacing for markdown rendering

* put in the reset key documentation

* clean up the file a little

* use LAYOUT_96_ansi

* add a second layer for lighting controls

* add in lighting support

* add QMK Configurator support

* use pragma once

* remove un needed matrix.c

* convert to GPIO methods

* turn on rgblight_enable and get rid of custom matrix

* set bootloadhid_bootloader to 1

* set bootmagic to lite and set it to k50

* add reset information to readme

* use i2c_master instead of custom i2c

* restore the custom i2c code

* introduce reset key and eep_rst in function layer 1

* fix up pip3 install commands

* fix up device and manufacturer names

* remove un needed comments

* add an ALL layout macro along with QMK Configurator support

* move budget96 into donutcables directory since he actually has different boards

* add a short donut cables blurb taken from his website

* update readme for make instructions to point to the new path

* Update keyboards/donutcables/budget96/config.h

+96 key atmega32a keyboard. 
+
+Keyboard Maintainer: [MechMerlin](https://github.com/mechmerlin)  
+Hardware Supported: Budget96 PCB  
+Hardware Availability: [DonutCables](https://donutcables.com/)  
+
+Make example for this keyboard (after setting up your build environment):
+
+    make donutcables/budget96:default
+
+Flashing
+
+**Reset Key:** Hold down the key located at `K00`, commonly programmed as left control while plugging in the keyboard. You may also hold down the key located at `K50`, commonly programmed as the `Esc` key. 
+
+ps2avr(GB) boards use an atmega32a microcontroller and a different bootloader. It is not flashable using the regular QMK methods. 
+
+Windows: 
+1. Download [HIDBootFlash](http://vusb.wikidot.com/project:hidbootflash).
+2. Place your keyboard into reset. 
+3. Press the `Find Device` button and ensure that your keyboard is found.
+4. Press the `Open .hex File` button and locate the `.hex` file you created.
+5. Press the `Flash Device` button and wait for the process to complete. 
+
+macOS:
+1. Install homebrew by typing the following:   
+    ```
+    /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
+    ```
+2. Install `crosspack-avr`.  
+    ```
+    brew cask install crosspack-avr
+    ```
+3. Install the following packages:
+    ```
+    brew install python
+    pip3 install pyusb
+    brew install --HEAD https://raw.githubusercontent.com/robertgzr/homebrew-tap/master/bootloadhid.rb
+
+4. Place your keyboard into reset. 
+5. Flash the board by typing `bootloadHID -r` followed by the path to your `.hex` file. 
+
+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).

+also hardware interrupt 0 on many devices) and USB D- to Port D bit 4. You may
+wire the lines to any other port, as long as D+ is also wired to INT0 (or any
+other hardware interrupt, as long as it is the highest level interrupt, see
+section at the end of this file).
