[Keyboard] Add TGR x SINGA Unikorn 60 (#6249)

* initial commit, copied from singa

* default 60_ansi LAYOUT implemented and tested workin

* add rgb underglow support bounded by ifdefs

* edit readme to provide information on reset procedure and on rgb underglow support

* improve the default keymap to have a second layer with function keys and even a RESET

* Add LAYOUT_all macro and discovered that split backspace uses an additional pin on the microcontroller

* fix up last line in readme

* Add QMK Configurator support

+# Unikorn 60
+
+60% PCB made for the TGR x SINGA Unikorn60. 
+
+
+Keyboard Maintainer: [MechMerlin](https://github.com/mechmerlin)  
+Hardware Supported: Unikorn 60 PCB  
+Hardware Availability: [Geekhack GB](https://geekhack.org/index.php?topic=98350.0)
+
+
+Make example for this keyboard (after setting up your build environment):
+
+    make unikorn:default
+
+This PCB can support RGB underglow. There are pads on the bottom of the PCB for the LED controller chip and for 17 RGB underglow LEDs. The Unikorn 60 case does not have acrylic pieces to properly display underglow effects. 
+
+To enable RGB lighting support, install the necessary components and set RGBLIGHT features in `rules.mk` like so:
+
+```
+RGBLIGHT_ENABLE = yes
+RGBLIGHT_CUSTOM_DRIVER = yes
+```
+
+
+Flashing
+
+ps2avr(GB) boards use an atmega32a microcontroller and a different bootloader. It is not flashable using the regular QMK methods. 
+
+**Reset Key:** Short the two holes labeled `FW_JP` beside the Tab key. At this time there is no reset key to press.   
+
+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 python3
+    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).

+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).

+ * runtime in the function usbFunctionDescriptor(). See usbdrv.h for more
+ * information about this function.
+ * Descriptor handling is configured through the descriptor's properties. If
+ * no properties are defined or if they are 0, the default descriptor is used.
+ * Possible properties are:
+ *   + USB_PROP_IS_DYNAMIC: The data for the descriptor should be fetched
+ *     at runtime via usbFunctionDescriptor(). If the usbMsgPtr mechanism is
+ *     used, the data is in FLASH by default. Add property USB_PROP_IS_RAM if

+ *   + USB_PROP_IS_RAM: The data returned by usbFunctionDescriptor() or found
+ *     in static memory is in RAM, not in flash memory.
+ *   + USB_PROP_LENGTH(len): If the data is in static memory (RAM or flash),
+ *     the driver must know the descriptor's length. The descriptor itself is
+ *     found at the address of a well known identifier (see below).
+ * List of static descriptor names (must be declared PROGMEM if in flash):

+ *   char usbDescriptorConfiguration[];
+ *   char usbDescriptorHidReport[];
+ *   char usbDescriptorString0[];
+ *   int usbDescriptorStringVendor[];
+ *   int usbDescriptorStringDevice[];
+ *   int usbDescriptorStringSerialNumber[];
+ * Other descriptors can't be provided statically, they must be provided
+ * dynamically at runtime.
+ *
+ * Descriptor properties are or-ed or added together, e.g.:
+ * #define USB_CFG_DESCR_PROPS_DEVICE   (USB_PROP_IS_RAM | USB_PROP_LENGTH(18))
+ *
+ * The following descriptors are defined:
