Add support for ST7789V display module (as on TTGO T-Display) (#1050)

Browse Source 
* TFT-LCD ST7789V of ESP32 TTGO.

This patch allows you to use TFT-LCD ST7789V of ESP32 TTGO

* Lots of polish and a few tweaks

* Add test

* Add color to core, take 1

* Where did those tabs come from?

* Fix lines too long

* Added color component

* Linted

* Rebase, SPI fix, test

* Shuffle bits

* One more thing...oops

* Image type fix...oops

* Make display_buffer use Color

* Fix BGR/RGB, remove predefined colors

* Fix all the things

* renamed colors to color

* migrate max7219
