Add SSD1306 OLED display support to TKC1800 (#2293)

* Add support for SSD1306 OLED display

* Correct keymap

Had tilde on keymap instead of grave, corrected.

* Winkeyless keymap

+Chocopad
+========
+
+A 4x4 macropad keyboard using Kailh PG1350 Lower Profile Choc switches.
+
+Keyboard Maintainer: Keebio  
+Hardware Supported: Chocopad PCB, Arduino Pro Micro  
+Hardware Availability: [Keebio](https://keeb.io)
+
+Make example for this keyboard (after setting up your build environment):
+
+    make chocopad: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.
