LVGL 9.0

For this v9 of LVGL I'm using this fork: git submodule add https://github.com/bwhitman/lvgl.git components/lvgl (In branch: tulip)

Since @bwhitman added the LV_COLOR_FORMAT_RGB332 that is missing so far in version 9 of LVGL.

v9: STEPS to check it out

git clone --recursive -b 16/lvgl-90 https://github.com/martinberlin/lv_port_esp32-epaper.git

That should do it. Should pull the repo in the 16/lvgl-90 branch and also additionally related drivers: https://github.com/martinberlin/lvgl_epaper_drivers/tree/lvgl-v9
