Add color text for each tilt (#26)

* add env for ttgo t-display

* add lcd code for tft_espi

* fixed typo in debugging print

* fixed width for t-display

* add usb ports

* show three tilts on a page

* remove debugging prints

* add method that returns color code

* use color for tilt and display temp on ttgo t-displat

* fix startup display
