add not-so-minidox handwire keyboard (#3061)

* add not-so-minidox handwire keyboard * corrected keymap * multiple adjustments to not_so_minidox keyboard * remove I2C master left define * update default layer set function * move solenoid code into userspace * minor adjustments to config.h * update keymaps to utilize userspace * move features and config to userspace, correct build issue * correct solenoid pin * adjust defaults for solenoid pin and enable * default solenoid to on for not_so_minidox * disable RGBLIGHT_SLEEP for xd75 * tweaking solenoid enable/disable in userspace and keymaps

+=====
+
+![not_so_minidox]()
+
+A slightly larger version of the MiniDox
+
+Keyboard Maintainer: mtdjr
+Hardware Supported: None yet/ProMicro
+
+Make example for this keyboard (after setting up your build environment):
+
+    make not_so_minidox/rev1:default
+
+See [build environment setup](https://docs.qmk.fm/build_environment_setup.html) then the [make instructions](https://docs.qmk.fm/make_instructions.html) for more information.
+
+Flashing
+-------
+Note: Most of this is copied from the Let's Split readme, because it is awesome
+
+From the root directory run `make PROJECT:KEYMAP:avrdude` for automatic serial port resolution and flashing.
+Example: `make not_so_minidox/rev1:default:avrdude`
+
+Choosing which board to plug the USB cable into (choosing Master)
+--------
+Because the two boards are identical, the firmware has logic to differentiate the left and right board.
+
+It uses two strategies to figure things out: look at the EEPROM (memory on the chip) or looks if the current board has the usb cable.
+
+The EEPROM approach requires additional setup (flashing the eeeprom) but allows you to swap the usb cable to either side.
+
+The USB cable approach is easier to setup and if you just want the usb cable on the left board, you do not need to do anything extra.
+
+### Setting the left hand as master
+If you always plug the usb cable into the left board, nothing extra is needed as this is the default. Comment out `EE_HANDS` and comment out `I2C_MASTER_RIGHT` or `MASTER_RIGHT` if for some reason it was set.
+
+### Setting the right hand as master
+If you always plug the usb cable into the right board, add an extra flag to your `config.h`
+```
+ #define MASTER_RIGHT
+```
+
+### Setting EE_hands to use either hands as master
+If you define `EE_HANDS` in your `config.h`, you will need to set the
+EEPROM for the left and right halves.
+
+The EEPROM is used to store whether the
+half is left handed or right handed. This makes it so that the same firmware
+file will run on both hands instead of having to flash left and right handed
+versions of the firmware to each half. To flash the EEPROM file for the left
+half run:
+```
+avrdude -p atmega32u4 -P $(COM_PORT) -c avr109 -U eeprom:w:eeprom-lefthand.eep
+// or the equivalent in dfu-programmer
+
+```
+and similarly for right half
+```
+avrdude -p atmega32u4 -P $(COM_PORT) -c avr109 -U eeprom:w:eeprom-righhand.eep
+// or the equivalent in dfu-programmer
+```
+
+NOTE: replace `$(COM_PORT)` with the port of your device (e.g. `/dev/ttyACM0`)
+
+After you have flashed the EEPROM, you then need to set `EE_HANDS` in your config.h, rebuild the hex files and reflash.
+
+Note that you need to program both halves, but you have the option of using
+different keymaps for each half. You could program the left half with a QWERTY
+layout and the right half with a Colemak layout using bootmagic's default layout option.
+Then if you connect the left half to a computer by USB the keyboard will use QWERTY and Colemak when the
+right half is connected.
